DESCRIPTION The IC generates either odd or even parity making The 74ACT280 is an advanced high-speed CMOS it flexible application. The word-length capability is 9 BIT PARITY GENERATOR CHECKER easly expanded by cascading. fabricated with sub-micron silicon gate and The device is designed to interface directly High double-layer metal wiring C2MOS tecnology. Speed CMOS systems with TTL, NMOS and It is composed of nine data inputs (A to I) and odd/ CMOS output voltage levels. even parity outputs (ODD and EVEN). The nine All inputs and outputs are equipped with data inputs control the output conditions. When protection circuits against static discharge, giving
