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 outputs.

The 74LCX257 is a non-inverting multiplexer.
When the ENABLE INPUT is held "High", all outputs become in high impedance state.
