74LS42 datasheet

 

Description :

These monolithic 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 availible for decoding by the NAND gates. Full decoding of valid input logic ensures that all outputs remain off for all invalid input conditions.

Features

1. All ouputs are high for invalid input conditions
2. Also for application as
(1) 4-Line-to-16-Line Decoders
(2) 3-Line-to-8-Line Decoders
3. Diode-Clamped Inputs
