DESCRIPTION

The AC280 is an advanced high-speed CMOS 9

BIT

fabricated with sub-micron silicon gate and

double-layer metal wiring C

ideal for low power applications mantaining high

speed operation similar to eqivalent Bipolar

Schottky TTL.

It is composed of nine data inputs (A to I) and

odd/even parity outputs ( ODD and EVEN). The

9 BIT PARITY GENERATOR/CHECKER

CHECKER

nine data inputs control the output conditions.

When the number of high level input is odd,

Conservely, when the output is even,

output is kept high and ODD low.

The IC generates either odd or even parity

making it flexible application.

The word-length capability is easily expanded by

cascading.

The device is designed to interface directly High

Speed CMOS systems with TTL, NMOS and

CMOS output voltage levels.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

ODD output is kept high and EVEN output low.
