54LS42 - BCD/Decimal Decoders

General Description

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 condition

Key Features

  • Y Diode clamped inputs Y Also for.
