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

Diode clamped inputs
Also for applications as 4-line-to-16-line decoders; 3-line-to-8-line decoders
All outputs are high for invalid input conditions
Alternate Military/Aerospace device (54LS42) is available. Contact a National Semiconductor Sales Office/Distributor for specifications.
