DL257D IC Quad 2-input multiplexer DIP-16

The DL257D is a TTL-based Quad 2-Input Data Selector/Multiplexer integrated circuit designed for digital signal routing, data selection, embedded systems, automation electronics, and logic control applications. The IC contains four independent 2-input multiplexers with common select and enable control lines inside a standard DIP16 through-hole package, making it suitable for breadboard prototyping, industrial electronics, educational projects, and PCB development.

Features:
  • Four independent 2-input multiplexers.
  • Compatible with 74257 and SN74LS257 IC families.
  • Common select input control.
  • 3-state output configuration.
  • TTL Low-Power Schottky technology.
  • Standard DIP16 through-hole package.
