Features

Description

• Buffered Inputs and Outputs

The ’HC42 and CD74HCT42 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 LS 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
