DEVICE DESCRIPTION
The CAT24C03/CAT24C05 is a 2-kb/4-kb CMOS Serial EEPROM device organized internally as 16/32 pages of 16 bytes each, for a total of 256x8/512x8 bits. These devices support both Standard (100kHz) as well as Fast (400kHz) I2C protocol.
Data is written by providing a starting address, then loading 1 to 16 contiguous bytes into a Page Write Buffer, and then writing all data to non-volatile memory in one internal write cycle. Data is read by providing a starting address and then shifting out data serially while automatically incrementing the internal address count.
Write operations can be inhibited for upper half of memory by taking the WP pin High.
External address pins make it possible to address up to eight CAT24C03 or four CAT24C05 devices on the same bus.

FEATURES
*Supports Standard and Fast I2C Protocol
*1.8 V to 5.5 V Supply Voltage Range
*16-Byte Page Write Buffer

DESCRIPTION
The SP720 is an array of SCR/Diode bipolar structures for ESD and over-voltage protection to sensitive input circuits.
The SP720 has 2 protection SCR/Diode device structures per input.
A total of 14 available inputs can be used to protect up to 14 external signal or bus lines.
Over-voltage protection is from the IN (pins 1-7 and 9-15) to V+ or V-.
The SCR structures are designed for fast triggering at a threshold of one +V BE diode threshold above V+ (Pin 16) or a -V BE diode threshold below V- (Pin 8).
From an IN input, a clamp to V+ is activated if a transient pulse causes the input to be increased to a voltage level greater than one V BE above V+.
A similar clamp to V- is activated if a negative pulse, one V BE less than V-, is applied to an IN input.

Description
SMP Surface Mount Power Cross Protection Fuses are primarily intended for use in telecommunication circuit applications requiring low current protection with high surge tolerance.
They are typically used to replace heat coil type devices.
They are designed to be placed between the line input and the surge arresting components (mov. gas tube, zenor diode, air gaps, etc.)
These fuses will withstand transient surge currents generated by lightning in accordance with the attached table.
SMP Fuses guard protected circuitry against sustained overload or short circuit conditions. Such sustained overloads may be generated by accidental contact between utility cables and phone lines (power line cross).
SMP Fuse are used in circuits to obtain compliance with the test requirements specified in UL 1950/60950 and Bellcore GR 1089.

DESCRIPTION
 The M74HC4852 is a dual four-channel analog MULTIPLEXER/DEMULTIPLEXER fabricated
with silicon gate C2MOS technology.
It is pin to pin compatible with the equivalent to standard HC4052 and MC14052, but features injection current effect control.
This makes this device especially suited for usage in automotive applications where voltages in excess of normal logic voltage are common.
The injection current effect control allows signals at disabled input channels to exceed the supply voltage range or go down ground without affecting the signal of the enabled analog channel.
This eliminates the need for external diode-resistor networks typically used to keep the analog channel signals within the supply voltage range.
This analog switch is bidirectional and digitally controlled.
It has two binary control inputs A and B to select 1 of 4 to be turned on, and connected to the output, and a INH input to disable all channels.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

* LOW POWER DISSIPATION: ICC = 2mA(MAX.) at TA=25°C
* INJECTION CURRENT PROTECTION: VDOUT<1mV at VCC=5V IIN≤1mA RS≤3.9KW
* "ON"RESISTANCE at TA=25°C:
- 215W TYP. (VCC = 3.0V)
- 150W TYP. (VCC = 4.5V)
- 160W TYP. (VCC = 6V)
* FAST SWITCHING: tpd = 8.6ns (TYP.) at TA = 25 °C, VCC = 4.5V
* WIDE OPERATING SUPPLY VOLTAGE RANGE: VCC = 2V TO 6V
* HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.)
* PIN AND FUNCTION COMPATIBLE WITH SERIES 4052, 4852
* LATCH-UP PERFORMANCE EXCEEDS 500mA (JESD 17)
