The 74LCX257 is a low voltage CMOS QUAD 2 CHANNEL MULTIPLEXER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power and high speed 3.3V applications; it can be interfaced to 5V signal environment for both inputs and outputs.
It is composed of four independent 2 channel multiplexers with common SELECT and ENABLE (OE) INPUT. The 74LCX257 is a non-inverting multiplexer. When the ENABLE INPUT is held "High", all outputs become in high impedance state. If SELECT INPUT is held "Low", "A" data is selected, when SELECT INPUT is "High", "B" data is chosen.
It has same speed performance at 3.3V than 5V AC/ACT family, combined with a lower power consumption.
All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage
