INTEGRATED CIRCUITS DATA SHEET 74LVC157A Quad 2-input multiplexer Product specification 2002 Mar 15 Supersedes data of 1998 Jul 29 Philips Semiconductors Product specification Quad 2-input multiplexer 74LVC157A FEATURES The 74LVC157A is a quad 2-input multiplexer which select four bits of data from two sources under the control of a • 5 V tolerant inputs for interfacing with 5 V logic common select input (S). The four outputs present the • Wide supply voltage range from 1.2 to 3.6 V selected data in the true (non-inverted) form. The enable input (E) is active LOW. When E is HIGH, all of the outputs • CMOS low power consumption (1Y to 4Y) are forced LOW regardless of all the other input • Direct interface with TTL levels conditions. Moving the data from two groups of regi
