DM74S280  
9-Bit Parity Generator/Checker  
General Description  
Features  
These universal, nine-bit parity generators/checkers utilize  
Schottky-clamped TTL high-performance circuitry, and fea-  
ture odd/even outputs to facilitate operation of either odd or  
even parity applications. The word-length capability is eas-  
ily expanded by cascading.  
Generates either odd or even parity for nine data lines  
Cascadable for N-bits  
Can be used to upgrade existing systems using MSI par-  
ity circuits  
Typical data-to-output delay14 ns  
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 connec-  
tion at pin 3. This permits the DM74S280 to be substituted  
for the 180 in existing designs to produce an identical func-  
tion, 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.
