Quad 2-input multiplexer
Rev. 3 — 31 December 2010
Product data sheet
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 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 74HC/HCT157. 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 74HC/HCT157 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)
The 74HC/HCT157 is identical to the 74HC158 but has non-inverting (true) outputs.
2. Features and benefits

this 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.

15.2 Definitions
nor in applications where failure or malfunction of an NXP Semiconductors
product can reasonably be expected to result in personal injury, death or
severe property or environmental damage. NXP Semiconductors accepts no
liability for inclusion and/or use of NXP Semiconductors products in such
equipment or applications and therefore such inclusion and/or use is at the
customer’s own risk.
Draft — The document is a draft version only. The content is still under
internal review and subject to formal approval, which may result in
modifications or additions. NXP Semiconductors does not give any
representations or warranties as to the accuracy or completeness of
information included herein and shall have no liability for the consequences of
use of such information.
Applications — Applications that are described herein for any of these
products are for illustrative purposes only. NXP Semiconductors makes no
representation or warranty that such applications will be suitable for the
specified use without further testing or modification.
Short data sheet — A short data sheet is an extract from a full data sheet
with the same product type number(s) and title. A short data sheet is intended
for quick reference only and should not be relied upon to contain detailed and
full information. For detailed and full information see the relevant full data
sheet, which is available on request via the local NXP Semiconductors sales
office. In case of any inconsistency or conflict with the short data sheet, the
full data sheet shall prevail.
Customers are responsible for the design and operation of their applications
and products using NXP Semiconductors products, and NXP Semiconductors
accepts no liability for any assistance with applications or customer product
design. It is customer’s sole responsibility to determine whether the NXP
Semiconductors product is suitable and fit for the customer’s applications and
products planned, as well as for the planned application and use of
customer’s third party customer(s). Customers should provide appropriate
design and operating safeguards to minimize the risks associated with their
applications and products.
Product specification — The information and data provided in a Product
data sheet shall define the specification of the product as agreed between
NXP Semiconductors and its customer, unless NXP Semiconductors and
customer have explicitly agreed otherwise in writing. In no event however,
shall an agreement be valid in which the NXP Semiconductors product is
deemed to offer functions and qualities beyond those described in the
Product data sheet.
NXP Semiconductors does not accept any liability related to any default,
damage, costs or problem which is based on any weakness or default in the
customer’s applications or products, or the application or use by customer’s
third party customer(s). Customer is responsible for doing all necessary
testing for the customer’s applications and products using NXP
Semiconductors products in order to avoid a default of the applications and
the products or of the application or use by customer’s third party
customer(s). NXP does not accept any liability in this respect.
15.3 Disclaimers
Limited warranty and liability — Information in this document is believed to
be accurate and reliable. However, NXP Semiconductors does not give any
representations or warranties, expressed or implied, as to the accuracy or
completeness of such information and shall have no liability for the
consequences of use of such information.
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.
In no event shall NXP Semiconductors be liable for any indirect, incidental,
punitive, special or consequential damages (including - without limitation - lost
profits, lost savings, business interruption, costs related to the removal or
replacement of any products or rework charges) whether or not such
damages are based on tort (including negligence), warranty, breach of
contract or any other legal theory.
Terms and conditions of commercial sale — NXP Semiconductors
products are sold subject to the general terms and conditions of commercial
sale, as published at http://www.nxp.com/profile/terms, unless otherwise
agreed in a valid written individual agreement. In case an individual
agreement is concluded only the terms and conditions of the respective
agreement shall apply. NXP Semiconductors hereby expressly objects to
applying the customer’s general terms and conditions with regard to the
purchase of NXP Semiconductors products by customer.
Notwithstanding any damages that customer might incur for any reason
whatsoever, NXP Semiconductors’ aggregate and cumulative liability towards
