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.

PIN AND FUNCTION COMPATIBLEWITH

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  
PIN CONNECTION AND IEC LOGIC SYMBOLS
