产品概述
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.
