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

nine data inputs control the output conditions.

When the number of high level input is odd,

ODD output is kept high and EVEN output low.

Conservely, when the output is even, ΣEVEN

output is kept high and ΣODD low.

OPERATING VOLTAGERANGE:

V_CC(OPR)= 2V to 6V

PIN AND FUNCTION COMPATIBLEWITH

74 SERIES280

IMPROVED LATCH-UP IMMUNITY

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.

DESCRIPTION

The AC280 is an advanced high-speed CMOS 9

BIT PARITY GENERATOR fabricated with

sub-micron silicon gate and double-layer metal

wiring C²MOS technology. It is ideal for low

power applications mantaining high speed

operation similar to equivalent Bipolar Schottky

TTL.

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