General Description
The MM74C150 and M M8 2C 1 9 mu lti plex 16 di gita l li ne s to
1 output. A 4-bit ad dre ss code determines th e p articular 1of-16 inputs which is routed to the output. The data is
inverted from input to output.
A strobe override places the output of MM74C15 0 in the
logical “1” state and the output of MM82C19 in the highimpedance state.
All inputs are protected from damage due to static discharge by diode clamps to V
and GND.
