BCD To Decimal Decoder (1 of 10)

Features

Description

• Buffered Inputs and Outputs

The Harris CD74HC42, CH74HCT42 BCD-to-Decimal

Decoders utilize silicon-gate CMOS technology to achieve

operating speeds similar to LSTTL decoders with the low

power consumption of standard CMOS integrated circuits.

These devices have the capability of driving 10 LSTLL loads

and are compatible with the standard 74LS logic family. One

of ten outputs (low on select) is selected in accordance with

the BCD input. Non-valid BCD inputs result in none of the
