Description
General part information
SN74LS42 Series
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 available for decoding by the NAND gates. Full decoding of valid input logic ensures that all outputs remain off for all invalid input conditions.
The '42A and 'LS42 feature inputs and outputs that are compatible for use with most TTL and other saturated low-level logic circuits. DC noise margins are typically one volt.
The SN5442A and SN54LS42 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN7442A and SN74LS42 are characterized for operation from 0°C to 70°C.
