9-Bit Odd/Even Parity Generator/Checker
Description
Functional Diagram
The CD54AC280/3A and CD54ACT280/3A are 9-bit odd/
even parity generator/checkers that utilize the Harris
Advanced CMOS Logic technology. Both even and odd par-
ity outputs are available for checking or generating parity
words up to nine bits long. Even parity is indicated (E out-
put is HIGH) when an even number of data inputs is HIGH.
Odd parity is indicated (O output is HIGH) when an odd
number of data inputs is HIGH. Parity checking for words
larger than nine bits can be accomplished by tying the E
output to any output of an additional AC/ACT280 parity
checker.
The CD54AC280/3A and CD54ACT280/3A are supplied in
14 lead dual-in-line ceramic packages (F suffix).
