74LCX157 Low voltage CMOS Quad 2 channel multiplexer with 5V tolerant inputs

The 74LCX157 is a low voltage CMOS Quad 2 channel multiplexer 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 inputs.

It consists of four 2-input digital multiplexer with common select and strobe inputs. It is a non-inverting multiplexer. When the STROBE input is held high selection of data is inhibited and all the outputs become low. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs.

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.
