description
The 74AC11191 is a synchronous, 4-bit binary reversible up/down counter. Synchronous counting operation
is provided by clocking all flip-flops simultaneously so that the outputs change coincident with each other when
instructed by the steering logic. This mode of operation eliminates the output counting spikes normally
associated with asynchronous (ripple clock) counters.
The outputs of the four flip-flops are triggered on a low-to-high-level transition of the clock input if the enable
input (CTEN) is low. A high at CTEN inhibits counting. The direction of the count is determined by the level of
the down/up (D/U) input. When D/U is low, the counter counts up and when D/U is high, it counts down.
These counters feature a fully independent clock circuit. Changes at the control inputs (CTEN and D/U) that
will modify the operating mode have no effect on the contents of the counter until clocking occurs. The function
of the counter will be dictated solely by the condition meeting the stable setup and hold times.
These counters are fully programmable; that is, the outputs may be preset to any number between 0 and 15
by placing a low on the load input and entering the desired data at the data inputs. The outputs will change to
agree with the data inputs independently of the level of the clock input. This feature allows the counter to be
used as a modulo-N divider by simply modifying the count length with the preset inputs.
Two outputs have been made available to perform the cascading function: ripple clock and maximum/minimum
count. The latter output produces a high-level output pulse with a duration approximately equal to one complete
cycle of the clock while the count is zero (all outputs low) counting down or maximum (15) counting up. The
ripple-clock output (RCO) produces a low-level output pulse under those same conditions but only while the
clock input is low. The counter can easily be cascaded by feeding the ripple clock output to the enable input
of the succeeding counter if parallel clocking is used, or to the clock input if parallel enabling is used. The
maximum/minimum count output can be used to accomplish look-ahead for high-speed operation.
The 74AC11191 is characterized for operation from − 40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
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.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
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.
