The SY10/100E175 are 9-bit latches. They also feature

a tenth latched output (ODDPAR) which is formed as the

odd parity of the nine data inputs (ODDPAR is HIGH if

an odd number of the inputs are HIGH).

The E175 can also be used to generate byte parity by

odd parity) and using ODDPAR as the byte parity output.

The LEN pin latches the data when asserted with a

logical high and makes the latch transparent when placed

at a logic low level.
