DESCRIPTION
The MA3690/1 chip set has three modes of operation: remote terminal, bus controller, and passive monitor It has a dual bus capability, requires minimum support hardware / software and is implemented on a radiation hard, CMOS/SOS process. For applications requiring access to Terminal Flag, a 48-Pin DIL MA3693 is available as an alternative to the MA3690.
As a remote terminal, the MA3690/1 is fully compatible with Mil-Std-1553B. The chip set obtained SEAFAC approval in December 1987. All options and mode commands specified by the Mil Std are implemented Full and meaningful use is made of status word bits and a comprehensive bit word is provided.
A unique mechanism has been incorporated that allows the subsystem to declare illegal commands legal, and vice versa, before the chip set services the command. It should be noted that use of this mechanism is optional and that the system defaults to normal operation if the option is not required. The chip set is easily interfaced to subsystem memory and is sufficiently flexible to ensure compatibility with a wide range of microprocessors.
As a bus controller the MA3690/1 has the ability to initiate all types of 1553B transfer on either of the two buses An instruction word is set up by the subsystem, prior to transmission, which contains details of transfer type and bus selection. Four bits of the instruction word have been used to specify the conditions under which the chip set will generate a subsystem interrupt. The most significant bits of the instruction word have been used to specify the conditions under which the chip set will perform an automatic retry and the number of retries to be carried out (max. 3). At the end of each instruction execution cycle, the chip set writes a report word into the subsystem memory; the contents of which give the subsystem an indication of the degree of success of the transfer.
The bus controller may be used in either of two configurations, i.e. single shot or table driven.
In the single shot configuration, the controller is under direct control from the subsystem (processor). In table driven configuration, the controller is given greater autonomy to execute a table of instructions held in either ROM or RAM.
As a passive monitor, the chip set will monitor all bus activity and pass any associated information to the subsystem. As the name implies, in this mode of operation, the chip set is truly passive and will not reply to command instructions.

FEATURES
*Radiation Hard to 1MRads (Si)
*High SEU Immunity, Latch-Up Free
*CMOS-SOS Technology
*All Inputs and Outputs Fully TTL or CMOS Compatible
*Military Temperature Range -55 to +125°C
*Dual Bus Capability
*Minimal Subsystem Interface
*Powerful Bus Control Facility
*Complete Remote Terminal Protocol
*SEAFAC Approved

DESCRIPTION
Maxwell Technologies’ 54LVTH162245 devices are 16-bit (dual-octal) non-inverting 3-state transceivers designed for low-voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. These devices can be used as two 8-bit transceivers or one 16-bit transceiver. The devices allow data transmission from the A bus to the B bus or form the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output enable (OE) input can be used to disable the device so that the buses are effectively isolated. The A-port outputs, which are designed to source or sink up to 12 mA, include equivalent 22-Ωseries resistors to reduce overshoot and undershoot.
Maxwell Technologies' patented RAD-PAK® packaging technology incorporates radiation shielding in the microcircuit package. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class S.

FEATURES
*A-Port outputs have equivalent 22-Ω series resistors, so no external resistors are required
*Support mixed-mode signal operation (5V input and output voltages with 3.3V VCC)
*Support unregulated battery operation down to 2.7V
*TypicalVOLP (output ground bounce) < 0.8V at VCC = 3.3V, TA = 25°C
*IOFF and power-up 3-state support hot insertion
*Bus hold on data inputs eliminates the need for external pullup/pulldown resistors
*Distributed VCC and GND pin configuration minimizes highspeed switching noise
*Flow-through architecture optimizes PCB layout
*Total dose hardness:
-100 krad (Si), depending upon space mission
*Package: 48 pin RAD-PAK® flat pack

Description
The Si9243EY is a monolithic bus transceiver designed to provide bidirectional serial communication in automotive diagnostic applications.
The device incorporates protection against overvoltages and short circuits to GND or VB.
The transceiver pin is protected and can be driven beyond the VBAT voltage.
The Si9243EY contains temperature and short circuit fault detection circuits.
In the transmit mode, load shorts and opens are generally detected by the processor
monitoring RXK and TX.
When the two mirror each other there is no fault, but the Si9243EY will turn off the K output in the event of over temperature or short circuit to VBAT to protect the IC.
The fault will be reset when TX toggles “high.”
TX is set “high” for receive only.
The RX output is capable of driving CMOS or 1 X LSTTL load.
The Si9243EY is built on the Siliconix BiC/DMOS process.
This process supports bipolar transistors, CMOS, and DMOS. An epitaxial layer prevents latchup.
The Si9243EY is available in a 8-pin SO package and operates over the automotive temperature range (–40 to 125C).

Features
* Single-Ended Transceiver
* Survives Shorts and Transients on Automotive Bus
* Wide Power Supply Voltage Range
* Fault Detection
* ISO 9141 Compatible

Description
Fairchild switch FST3125 provides four high-speed CMOS TTL-compatible bus switches.
The low on resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.
The device is organized as four one1-bit switches with separate /OE inputs.
When /OE is LOW, the switch is ON and port A is connected to port B.
When /OE is HIGH, the switch is OPEN and a high-impedance state exists between the two ports.

Features
* 4Ω Switch Connection between Two Ports
* Minimal Propagation Delay through the Switch
* Low ICC
* Zero Bounce in Flow-through Mode
* Control Inputs Compatible with TTL Level
