General Description
AH174 is a single-digital-output Hall-effect sensor for high temperature operation. The device includes an on-chip Hall voltage generator for magnetic sensing, an amplifier to amplify Hall voltage, and a comparator to provide switching hysteresis for noise rejection, and an open-collector output pre-driver. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. While the magnetic flux density (B) is larger than threshold Bop, the OUT pin turns off (High). If B removed toward Brp, the OUT pin is latched “off” state prior to B < Brp. When B < Brp, the OUT pin go into “ on ” state.

General Description
ATS276/277 are integrated Hall sensors with output drivers, mainly designed for electronic commutation of brush-less DC Fan. This IC internally includes the regulator, protecting diode, Hall plate, amplifier, comparator, and a pair of complementary open-collector outputs (DO, DOB).
While the magnetic flux density (B) is larger than operate point (Bop), DO will turn on (low), and meanwhile DOB will turn off (high). Each output is latched until B is lower than release point (Brp), and then DO、DOB transfer each state.
For DC fan application, sometimes need to test power reverse connection condition. Internal diode only protects chip-side but not for coil-side. If necessary, add one external diode to block the reverse current from coil-side.

Features
*On-chip Hall sensor with two different sensitivity and hysteresis settings for ATS276/277
*3.5V to 20V operating voltage
*400mA (avg) output sink current
*Build-in protecting diode only for chip reverse power connecting
*-20°C to 85°C operating temperature
*Low profile 4 pin SIP package

Applications
*Dual-coil Brush-less DC Motor
*Dual-coil Brush-less DC Fan
*Revolution Counting
*Speed Measurement

The S-8130AA is a temperature switch with a latch function having a built-in semiconductor temperature sensor with the accuracy of ±2.5°C. The output signal is inverted when the temperature is detected, and latched until a reset signal input or a detection of the power voltage lowering.
Low voltage operation down to 2.2 V is possible and the current consumption is low, 15 μA (typ.), due to CMOS configuration.
The S-8130AA consists of a temperature sensor having the temperature coefficient of −13 mV/°C, a reference voltage source, a comparator, voltage detection circuit, and noise suppression circuit all of which are enclosed in 8-Pin MSOP package.
Since the temperature range of this IC is −40 to +100 °C, it is possible to achieve the extensive application for temperature control.

Features
*Detection temperature : +60 to +95°C, 5°C step
*Detection accuracy : ±2.5°C
*VSS grounded temperature voltage output
*Low voltage operation : VDD (min.)=2.2 V
*Low current consumption : 15 μA typ. (+25°C)
*Output logic level is fixed by the latch after temperature detection
*Noise suppression at temperature detection
*Package : 8-Pin MSOP

General Description
 The CD4724BC is an 8-bit addressable latch with three address inputs (A0–A2), an active low enable input (E), active high clear input (CL), a data input (D) and eight outputs (Q0–Q7).
Data is entered into a particular bit in the latch when that is addressed by the address inputs and the enable (E) is LOW. Data entry is inhibited when enable (E) is HIGH.
 When clear (CL) and enable (E) are HIGH, all outputs are LOW. When clear (CL) is HIGH and enable (E) is LOW, the channel demultiplexing occurs. The bit that is addressed has an active output which follows the data input while all unaddressed bits are held LOW. When operating in the addressable latch mode (E = CL = LOW), changing more than one bit of the address could impose a transient wrong address. Therefore, this should only be done while in the memory mode (E = HIGH, CL = LOW).

Features
* Wide supply voltage range: 3.0V to 15V
* High noise immunity: 0.45 VDD (typ.)
* Low power TTL compatibility: fan out of 2 driving 74L or 1 driving 74LS
* Serial to parallel capability
* Storage register capability
* Random (addressable) data entry
* Active high demultiplexing capability
* Common active high clear

• Total dose hardness:
- > 100 krad (Si), dependent upon space mission
• Single event effect:
- SELTH : No LU > 119 MeV/mg/cm2
• Package: 48 pin RAD-PAK® flat package
• Operating temperature range: - 55 to 125°C
• Distributed VCC and GND pin configuration minimizes highspeed switching noise
• Supports mixed-mode signal operation
- 5V input and output voltages with 3.3V VCC
• Supports unregulated battery operation down to 2.7V
• Typical VOLP (output ground bounce) < 0.8V at VCC=3.3V, TA=25°C
• Latch-up performance exceeds 500mA per JEDEC standard
• Supports live insertion
• Bus-hold data inputs eliminate the need for external pullup resistors

DESCRIPTION:
Maxwell Technologies’ 54LVTH16373 16-bit transparent Dtype latches with 3-state output features a greater than 100 krad (Si) total dose tolerance, dependent upon space mission.
The 54LVTH16373 is designed for low voltage (3.3V) VCC operation, but with the capability to provide a TTL interface to a 5V system environment. It is suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
 
 The 54LVTH16373 can be used as two 8-bit latches or one 16-bit latch. When the latch-enable (LE) input is low, the Q output are latched at the levels set up at the data (D) inputs. When LE is high, the Q outputs follow the D inputs. A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state or a high impedance state. In the high impedance state, the outputs neither load nor drive the bus lines significantly. The high impedance state and the increased drive provide the capability to drive bus lines without the need for interface or pullup components. OE does not affect internal operations of the latch. Old data can be retained or new data can be entered while the outputs are in the high impedance state.

 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.
