Description

This decoder MM74HC42 utilizes advanced silicon-gate CMOS technology.

Data on the four input pins select one of the 10 outputs corresponding to the value of the BCD number on the inputs.

An output of MM74HC42 will go low when selected, otherwise it remains high. If the input data is not a valid BCD number all outputs will remain high. The circuit has high noise immunity and low power consumption usually associated with CMOS circuitry, yet also has speeds comparable to low power Schottky TTL (LS-TTL) circuits, and is capable of driving 10 LS-TTL equivalent loads.

All inputs of MM74HC42 are protected from damage due to static discharge by diodes to VCC and ground.
