74LCX257 LOW VOLTAGE CMOS QUAD 2-CHANNEL MULTIPLEXER

duThe 74LCX257 is a low voltage CMOS QUAD 2 roCHANNEL MULTIPLEXER (3-STATE) fabricated with sub-micron silicon gate and double-layer Pmetal wiring C2MOS technology. It is ideal for low tepower and high speed 3.3V applications; it can be leinterfaced to 5V signal environment for both inputs and outpu.
