MM54HC280/MM74HC280
9-Bit Odd/Even Parity Generator/Checker
General Description
The MM54HC280/MM74HC280 utilizes advanced silicongate
CMOS technology to achieve the high noise immunity
and low power consumption of standard CMOS integrated
circuits. It possesses the ability to drive 10 LS-TTL loads.
This parity generator/checker features odd/even outputs to
facilitate operation of either odd or even parity applications.
The word length capability is easily expanded by cascading
devices. The 54HC/74HC logic family is speed, function,
and pinout compatible with the standard 54LS/74LS family.
All inputs are protected from damage due to static discharge
by internal diode clamps to VCC and ground.
