DM74AS286 9-Bit Parity Generator/Checker with Bus-Driver Parity I/O Port
October 1986
Revised April 2000
DM74AS286
9-Bit Parity Generator/Checker
with Bus-Driver Parity I/O Port
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 DM74AS286 can be used to upgrade the performance
of most systems utilizing the DM74AS280 parity generator/
checker. Although the DM74AS286 is implemented without
expander inputs, the corresponding function is provided by
the availability of an input pin XMIT. XMIT is a control line
which makes parity error output active and parity an input
port when HIGH; when LOW, parity error output is inactive
and parity becomes an output port. In addition, parity I/O
control circuitry contains a feature to keep the I/O port in
the 3-STATE during power UP or DOWN to prevent bus
glitches.
