8-Input Multiplexer

General Description

The 'AC/'ACT151 is a high-speed 8-input digital multiplexer.

It provides, in one package, the ability to select one line of

data from up to eight sources. The 'AC/'ACT151 can be used

as a universal function generator to generate any logic func-

tion of four variables. Both true and complementary outputs

are provided.

Features

■ICC reduced by 50%

■Outputs source/sink 24 mA

■'ACT151 has TTL-compatible inputs

■Standard Microcircuit Drawing (SMD)

Functional Description

The 'AC/'ACT151 is a logic implementation of a single pole,

8-position switch with the switch position controlled by the

state of three Select inputs, S0, S1, S2. Both true and com-

plementary outputs are provided. The Enable input (E) is

active LOW. When it is not activated, the complementary out-

put is HIGH and the true output is LOW regardless of all other

inputs. The logic function provided at the output is:

Z = E • (I0 • S0 • S1 • S2 + I1 • S0 • S1 • S2 +

I2 • S0 • S1 • S2 + I3 • S0 • S1 • S2 + I4 • S0 • S1 • S2 + I5 • S0 •

S1 • S2 + I6 • S0 • S1 • S2 + I7 • S0 • S1 • S2)

The 'AC/'ACT151 provides the ability, in one package to se-

lect from eight sources of data or control information. By

proper manipulation of the inputs, the 'AC/'ACT151 can pro-

vide any logic function of four variables and its complement.

and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are

sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.

TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard

warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where

mandated by government requirements, testing of all parameters of each product is not necessarily performed.

TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and

applications using TI components. To minimize the risks associated with customer products and applications, customers should provide

adequate design and operating safeguards.

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,

or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information

published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a

warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual

property of the third party, or a license from TI under the patents or other intellectual property of TI.

express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not

responsible or liable for any such statements.

TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably

be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing

such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and

acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products

and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be

provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in

such safety-critical applications.

TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are

specifically designated by TI as military-grade or "enhanced plastic."Only products designated by TI as military-grade meet military

specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at

the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.

TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are

designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated

products in automotive applications, TI will not be responsible for any failure to meet such requirements.
