16-Line to 1-Line Multiplexer 3-STATE •

16-Line to 1-Line Multiplexer

General Description

The MM74C150 and M M8 2C19 multiplex 16 digital line 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 t he output of MM74C150 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

CC

and GND.

Features

■ Wide supply voltage range: 3.0V to 15V

■ Guaranteed noise margin: 1.0V

■ High noise immunity: 0.45 V
