Quad 2-input multiplexer
Rev. 3 — 10 September 2020
Product data sheet
1. General description
The 74AHC/AHCT157 are high-speed Si-gate CMOS devices and are pin compatible with Low
Power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.
The 74AHC/AHCT157 are quad 2-input multiplexer which select 4 bits of data from two sources
under the control of a common data select input (S). The enable 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 74AHC/AHCT157. The state of the common data select input (S) determines the particular
register from which the data comes. 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
variables with one variable common. The 74AHC/AHCT157 is logic implementation of a 4-pole,
2-position switch, where the position of the switch is determine 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)

[1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V).
[2] tpd is the same as tPLH and tPHL
.
[3] CPD is used to determine the dynamic power dissipation PD (μW).
PD = CPD x VCC 2 x fi + Σ(CL x VCC 2 x fo) where:
fi = input frequency in MHz;
fo = output frequency in MHz;
CL = output load capacitance in pF;

Definitions
Limiting values — Stress above one or more limiting values (as defined in
the Absolute Maximum Ratings System of IEC 60134) will cause permanent
damage to the device. Limiting values are stress ratings only and (proper)
operation of the device at these or any other conditions above those
given in the Recommended operating conditions section (if present) or the
Characteristics sections of this document is not warranted. Constant or
repeated exposure to limiting values will permanently and irreversibly affect
the quality and reliability of the device.
