DM74AS280
9-Bit Parity Generator/Checker
General Description
These universal, 9-bit parity generators/checkers utilize
advanced Schottky high performance circuitry and feature
odd/even outputs to facilitate operation of either odd or
even parity applications. The word length capability is eas-
ily expanded by cascading.
The DM74AS280 can be used to upgrade the performance
of most systems utilizing the ’180 parity generator/checker.
Although the DM74AS280 is implemented without
expander inputs, the corresponding function is provided by
the availability of an input at pin 4 and no internal connec-
tion at pin 3. This permits the DM74AS280 to be substi-
tuted for the ’180 in existing designs to produce identical
function even if DM74AS280s are mixed with existing
’180s.
Features
s Generates either odd or even parity for nine data lines
s Inputs are buffered to lower the drive requirements
s Can be used to upgrade existing systems using MSI
parity circuits
s Cascadable for N-bits
s Advanced oxide-isolated, ion-implanted Schottky
TTL process
s Switching specifications at 50 pF
s Switching specifications guaranteed over full
temperature and VCC range
