The 74AXP1G157 is a single 2-input multiplexer which select data from two data inputs (I0 andI1) under control of a common data select input (S). The state of the common data selectinput determines the particular register from which the data comes. The output (Y)presents the selected data in the true (non-inverted) form.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise andfall times.

This device ensures very low static and dynamic power consumption across the entireVCC range from 0.7 V to 2.75 V. It is fully specified for partial powerdown applications using IOFF. The IOFF circuitry disables theoutput, preventing the potentially damaging backflow current through the device when itis powered down.
