HLF 74LS156 Dual 2-to-4 Line Decoder/Demultiplexer with Open-Collector Outputs – DIP16 | High-Speed TTL Logic | 4.75V–5.25V, 0°C to +70°C | Through-Hole Package

The HLF 74LS156 is a high-performance dual 2-to-4 line decoder/demultiplexer IC designed using Low-Power Schottky TTL (LS) technology. Each decoder section provides active-low, open-collector outputs, allowing for wired-AND connections and direct interface with multiple logic levels.

With two independent 2-to-4 decoders, the device efficiently expands digital addressing and data routing capabilities in microprocessor systems, memory selection, and control logic applications. Operating from 4.75V to 5.25V over a temperature range of 0°C to +70°C, the DIP16 through-hole package ensures fast switching performance, excellent noise immunity, and robust TTL compatibility.
