FEATURES
DESCRIPTION
The 74F280B is a 9-bit Parity Generator or Checker commonly used
to detect errors in high speed data transmission or data retrieval
systems. Both Even (
for generating or checking even or odd parity on up to 9 bits.
The Even (
inputs (I
odd number of Data inputs are High.
Expansion to larger word sizes is accomplished by tying the Even
(
final stage. This expansion scheme allows an 81-bit data word to be
checked in less than 20ns.
