74HC157 datasheet

Description :

The 74HC157, 74HCT157, 74HC158, and ’HCT158 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.


1. Low-power dissipation

2. Complies with JEDEC standard no. 7A

3.  Input levels:

(1) For 74HC157: CMOS level

(2) For 74HCT157: TTL level

4. Non-inverting data path
