SN74LS42NS TI BCD-to-Decimal Decoder | 16-SO | 4-Bit Input, Active Low Output

Product Overview

The SN74LS42NS is a BCD-to-decimal decoder/demultiplexer from Texas Instruments, designed for high-performance digital systems. It converts a 4-bit Binary Coded Decimal (BCD) input into one of ten mutually exclusive active-low outputs. The device is fabricated using advanced low-power Schottky technology, providing a perfect balance of speed and power consumption. Housed in a compact 16-SO package, it is ideal for space-constrained applications requiring reliable decoding functions.
