74LVC157A-Q100 Datasheet | NXP Semiconductors

Quad 2-input multiplexer Rev. 2 - 2 May 2013 Product data sheet 1. General description The 74LVC157A-Q100 is a quad 2-input multiplexer which select four bits of data from two sources under the control of a mon select input (S). The four outputs present the selected data in the true (non-inverted) form. The enable input (E) is active LOW. When pin E is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all the other input conditions. Moving the data from two groups of registers to four mon output buses is a mon use of the 74LVC157A-Q100. The state of the mon data select input (S) determines the particular register from which the data es. It can...
