BCD to Decimal Decoders

Fairchild Semiconductor 

March 1998

DM7442A

BCD to Decimal Decoders

General Description

These BCD-to-decimal decoders consist of eight inverters

and ten, four-input NAND gates. The inverters are connected

in pairs to make BCD input data available for decoding by

the NAND gates. Full decoding of input logic ensures that all

outputs remain off for all invalid (10–15) input conditions.

Features

n Diode clamped inputs

n Also for application as 4-line-to-16-line decoders;

3-line-to-8-line decoders

n All outputs are high for invalid input conditions

n Typical power dissipation 140 mW

n Typical propagation delay 17 ns

n Alternate Military/Aerospace device (5442A) is available.
