description

These monolithic BCD-to-decimal decoders consist of eight inverters andten four-input NAND gates. The inverters are connected in pairs to make BCDinput data available for decoding by the NAND gates. Full decoding of validinput logic ensures that all outputs remain off for all invalid input conditions.

The '42A and 'LS42 feature inputs and outputs that are compatible for usewith most TTL and other saturated low-level logic circuits. DC noise marginsare typically one volt.

The SN5442A and SN54LS42 are characterized for operation over the fullmilitary temperature range of -55°C to 125°C. The SN7442A and SN74LS42are characterized for operation from 0°C to 70°C.
