74HC157 Datasheet – Quad 2-Input Multiplexer ( PDF )

Part Number : 74HC157

Function : High-Speed CMOS Logic Quad 2-Input Multiplexer

Package : DIP, SOIC 16 Pin

Manufacturers : Texas Instruments


74HC157 Multiplexer


Description :

The 74HC157, 74HCT157, 74HC158, and 74HCT158 are quad 2-input multiplexers which select four bits of data from two sources under the control of a common Select input (S).

The Enable input (E) is active Low. When (E) is High, all of the outputs in the 158, the inverting type, (1Y-4Y) are forced High and in the 157, the non-inverting type, all of the outputs (1Y-4Y) are forced Low, regardless of all other input conditions.
