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 patible with standard CMOS outputs; with pullup resistors, they are patible 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 acmodated 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...
