The 74LCX257 is a low voltage CMOS quad 2-channel multiplexer (3-STATE) fabricated with sub-micron silicon gate technology. It is designed for low power and high speed 3.3V applications and can be interfaced to 5V signal environments for both inputs and outputs. The device features power down protection on inputs and outputs, symmetrical output impedance, and balanced propagation delays.
