CD74HC42 (ACTIVE) High Speed CMOS Logic 1-of-10 BCD to Decimal Decoder

High Speed CMOS Logic 1-of-10 BCD to Decimal Decoder - CD74HC42
Datasheet
 

Description

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 outputs being selected (all outputs are high).
