74S280 - 9-Bit Parity Generator/Checker
74S280 - 9-Bit Parity Generator/Checker
These universal, nine-bit parity generators/checkers utilize
Schottky-clamped TTL high-performance circuitry, and feature
odd/even outputs to facilitate operation of either odd or
even parity applications. The word-length capability is easily
expanded by cascading.
The DM74S280 can be used to upgrade the performance
of most systems utilizing the DM74180 parity generator/
checker. Although the DM74S280 is implemented without
expander inputs, the corresponding function is provided by
the availability of all input at pin 4, and no internal connection
at pin 3. This permits the DM74S280 to be substituted
for the 180 in existing designs to produce an identical function,
even if DM74S280’s are mixed with existing 180’s.
Input buffers are provided so that each input represents
only one normal 74S load, and full fan-out to 10 normal
Series 74S loads is available from each of the outputs at
low logic levels. A fan-out to 20 normal Series 74S loads is
provided at high logic levels, to facilitate connection of
unused inputs to used inputs.
