Semiconductor
DM54180/DM74180 9-Bit Parity Generators/Checkers
General Description
These universal 9-bit (8 data bits plus 1 parity bit) parity
generators/checkers feature odd/even outputs and control
inputs to facilitate operation in either odd or even parity ap-
plications. Depending on whether even or odd parity is be-
ing generated or checked. the even or odd input can be
utilized as the parity or 9th-bit input. The word-length capa-
bility is easily expanded by cascading.
Input buffers are provided so that each data input repre-
sents only one normalized series 54/74 load. A full fan-out
to 10 normalized series 54/74 loads is available from each
of the outputs at a low logic level. A fan-out to 20 normal-
ized loads is provided at a high logic level to facilitate the
connection of unused inputs to used inputs.
