13-input parity checker/generator
DESCRIPTION
The HEF4531B is a parity checker/generator with 13 parity
inputs (I0 to I12) and a parity output (O). When the number
of parity inputs that are HIGH is even, the output is LOW.
When the number of parity inputs that are HIGH is odd, the
output is HIGH. For words of 12 bits or less, the output can
be used to generate either odd or even parity by
appropriate termination of the unused parity input(s). For
words of 14 or more bits, the devices can be cascaded by
connecting the output of one device to any parity input of
another device. When cascading devices, it is
recommended that the output of one device be connected
to the I12 input of the other device since there is less delay
to the output from the I12 input than from any other input
(I0 to I11).
