1. General description
The 74HC157; 74HCT157 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL. It is specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT157 are quad 2-input multiplexers which select 4 bits of data from two
sources under the control of a common data select input (S). The en able input (E) is
active LOW. When E is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of
all other input conditions.
Moving the data from two groups of registers to four common output buses is a common
use of the 74HC/HCT157. The state of the common data select input (S) determines the
particular register from which the data come s. It can also be used as function generator.
The device is useful for implementing highly irregular logic by generating any four of the
16 different functions of two var iab les with on e va ria ble comm on . Th e 74HC /HC T1 5 7 is
logic implementa tion of a 4-pole, 2-position switch, where the position of the switch is
determined by the logic levels applied to S.
The logic equations are:
1Y = E (1I1 S+1I0 S)
2Y = E (2I1 S+2I0 S)
3Y = E (3I1 S+3I0 S)
4Y = E (4I1 S+4I0 S)
The 74HC/HCT 15 7 is ide nt ical to the 74 HC 15 8 bu t ha s no n-i nv er tin g (tr ue ) outpu ts.

pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
