9-Input Parity Checker/Generator
General Description
The DM93S62 is a very high speed 9-input parity checker/
generator for use in error detection and error correction
applications. The DM93S62 provides odd and even parity
for up to nine data bits. The even parity output (PE) is
HIGH if an even number of inputs are HIGH and E is LOW.
The odd parity output (PO) will be HIGH if an odd number
of inputs are HIGH and E is LOW. A HIGH level on the
Enable (E) input forces both outputs LOW.
