ON Semiconductor 74LCX257MTC - Multiplexer IC

The ON Semiconductor 74LCX257MTC is a high-performance, quad 2-input multiplexer with 5V tolerant inputs and outputs. This integrated circuit (IC) is part of the LCX family, designed to offer low voltage operation with the capability to interface to a 5V signal environment. The 74LCX257MTC is fabricated with an advanced CMOS technology to achieve high-speed operation while maintaining CMOS low power dissipation.

This multiplexer device allows the selection of one of two inputs for each section by controlling the select input. The four outputs present the selected data in the true (non-inverted) form. The select input controls the data flow of the multiplexers. The OE input can be used to disable the output stage, providing high impedance outputs and thus allowing for the busing of the outputs. This feature is particularly useful in applications where multiple sources are connected to a data bus.

The 74LCX257MTC operates from a 2.3V to 3.6V VCC supply, making it suitable for interfacing with both 3.3V and 2.5V logic levels. The low on-resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.
