SN74HC257N IC MULTIPLEXER 4 X 2:1 16DIP

The SN74HC257N is a high-speed quad 2-to-1 line multiplexer with 3-state outputs. This integrated circuit selects one of two data sources for each of the four channels based on the state of a common select input. The selected data is then routed to the corresponding output. The device features an output enable (OE) input that, when high, forces all outputs to a high-impedance state, regardless of the select input or data inputs. This 3-state capability allows for easy busing of multiple devices. The SN74HC257N is fabricated using silicon gate CMOS technology, offering high noise immunity and low power consumption. It is specified in compliance with JEDEC standard no. 7-A. The 16DIP (Dual In-line Package) makes it easy to use in breadboard and prototyping applications.

This multiplexer is ideal for applications where multiple data sources need to be selected and routed to a single output, and where busing is required. The quad configuration allows for handling four independent channels simultaneously, making it suitable for parallel data processing and signal routing. The 3-state outputs provide a convenient way to disable the outputs, allowing for easy control, testing, and bus sharing. The SN74HC257N is commonly used in data selection, signal routing, and logic function generation in various digital systems. Its high speed, low power consumption, and 3-state outputs make it a versatile choice for a wide range of applications.

Key features of the SN74HC257N include its high-speed operation, with typical propagation delays of around 13ns at 5V.
