DM74S158N

Signal Switches, Multiplexers, Decoders Overview

The DM74S158N is a Schottky TTL quad multiplexer housed in a 16-lead Plastic Dual-In-Line Package (PDIP). It contains four independent 2-line to 1-line data selectors with inverted outputs. The device features buffered inputs and outputs, ensuring full on-chip data selection capability. It operates within a standard temperature range up to 70 °C and utilizes the Advanced Schottky process for improved switching performance compared to standard TTL counterparts.
