Nexperia 74LVC157ADB,112

The 74LVC157A is a quad 2-input multiplexer that selects four bits of data from two sources under the control of a common data select input (S). The four outputs present the selected data in true (non-inverting) form. The enable input (E) is active LOW. When pin E is HIGH, all outputs (1Y through 4Y) are forced LOW regardless of all other input conditions. A common application of the 74LVC157A is to move data from two groups of registers to four common output buses. The state of the common data select input (S) determines which particular register the data comes from. It can also be used as a function generator. By generating any 4 of the 16 different functions of two variables with one common variable, it is useful for implementing highly irregular logic. The device is the logic implementation of a 4-pole, 2-position switch, where the switch position is determined by the logic level applied to pin S. The inputs can be driven by 3.3 V or 5 V devices. This feature allows these devices to be used as translators in mixed 3.3 V and 5 V applications.
