The CAT1021, CAT1022 and CAT1023 are complete memory and supervisory solutions for microcontroller-based systems. A 2k-bit serial EEPROM memory and a system power supervisor with brown-out protection are integrated together in low power CMOS technology. Memory interface is via a 400kHz I2C bus. The CAT1021 and CAT1023 provide a precision VCC sense circuit and two open drain outputs: one (RESET) drives high and the other (RESET) drives low whenever VCC falls below the reset threshold voltage. The CAT1022 has only a RESET output and does not have a Write Protect input. The CAT1021 also has a Write Protect input (WP). Write operations are disabled if WP is connected to a logic high. All supervisors have a 1.6 second watchdog timer circuit that resets a system to a known state if software or a hardware glitch halts or “hangs” the system. For the CAT1021 and CAT1022, the watchdog timer monitors the SDA signal. The CAT1023 has a separate watchdog timer interrupt input pin, WDI.

The 74LX1G14 is a low voltage CMOS SINGLE SCHMITT INVERTER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for 1.65 to 5.5 VCC operations and low power and low noise applications. The internal circuit is composed of 3 stages including buffer output, which provide high noise immunity and stable output. Power down protection is provided on input and output and 0 to 7V can be accepted on inputs with no regard to the supply voltage. It can be interfaced to 5V signal environment for inputs in mixed 3.3/5V system. Pin configuration and function are the same as those of the 74LX1G04 but the 74LX1G14 has hysteresis. This together with its schmitt trigger function allows it to be used on line receivers with slow rise/fall input signals. The input is equipped with protection circuits against static discharge, giving it ESD immunity and transient excess voltage.

The 74LVQ280 is a low voltage CMOS 9 bit parity generator fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and low noise 3.3V applications. It is composed of nine data inputs (A to I) and odd/ even parity outputs (ΣODD and ΣEVEN). The nine data inputs control the output conditions. When the number of high level input is odd, ΣODD output is kept high and ΣEVEN output low. Conversely, when the number of high level is even, ΣEVEN output is kept high and ΣODD low. The IC generates either odd or even parity making it flexible application. The word-length capability is easily expanded by cascading. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.

The AC/ACT151 is a high-speed 8-input digital multiplexer. It provides the ability to select one line of data from up to eight sources. The AC/ACT151 can be used as a universal function generator to generate any logic function of four variables.

SN54BCT374, SN74BCT374 is an 8-bit D flip-flop produced by Texas Instruments. Its feature is that it has 3-state outputs, which can be used to drive high-capacitance or relatively low-impedance loads. It is suitable for implementing buffer registers, I/O ports, bidirectional bus drivers and working registers.

54150 and 54151A are data selectors/multiplexers that can select the desired data source. 54150 can select 16 data sources, and 54151A can select 8 data sources. 54150 and 54151A both have a programmable input that must be at a low logic level to enable these devices.
