odd/even parity outputs (ΣODD and ΣEVEN). The
nine data inputs control the output conditions.
When the number of high level input is odd,
ΣODD output is kept high and ΣEVEN output low.
Conservely, when the output is even, ΣEVEN

operation similar to equivalent Bipolar Schottky
TTL.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
