SEMICONDUCTOR TECHNICAL DATA
9-Bit Odd/Even Parity Generator/Checker
High–Performance Silicon–Gate CMOS
The MC74HC280 is identical in pinout to the LS280. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. This circuit consists of 9 data–bit inputs (A through I) and 2 outputs (Even Parity and Odd Parity) to allow both odd and even parity applications. Words greater than 9–bits can be accommodated by cascading other HC280 devices. This device can be used in systems utilizing the LS180 parity generator/ checker. Although the HC280 does not have expander inputs, the corresponding function is provided by an input at pin 4 and the absence of any connection at pin 3.
