Overview

HD74AC280/HD74ACT280 9-bit Parity Generator/Checker Description The HD74AC280/HD74ACT280 is a high-speed parity generator/checker that accepts nine bits of input data and detects whether an even or an odd number of these inputs is High.
If an even number of inputs is High, the Sum Even output is High.
If an odd number is High, the Sum Even output is Low.
The Sum Odd output is the complement of the Sum Even output.
Features • Outputs Source/Sink 24 mA • HD74ACT280 has TTL-Cmpatible Inputs Pin Arrangement I6 1 I7 2 NC 3 I8 4 ΣE 5 ΣO 6 GND 7 (Top view) 14 VCC 13 I5 12 I4 11 I3 10 I2 9 I1 8 I0 HD74AC280/HD74ACT280 Logic Symbol I0 I1 I2 I3 I4 I5 I6 I7 I8 ΣO ΣE Pin Names I0 – I8 ...
