description/ordering information  
These 8-bit latches feature 3-state outputs  
designed specifically for driving highly capacitive  
or relatively low-impedance loads. The devices  
are particularly suitable for implementing buffer  
registers, I/O ports, bidirectional bus drivers, and  
working registers.

(TOP VIEW)  
The eight latches are D-type transparent latches.  
When the latch-enable (LE) input is high, the Q  
outputs follow the data (D) inputs. When LE is  
taken low, the Q outputs are latched at the logic  
levels set up at the D inputs.

A buffered output-enable (OE) input can be used  
to place the eight outputs in either a normal logic  
state (high or low logic levels) or the  
high-impedance state. In the high-impedance  
state, the outputs neither load nor drive the bus  
lines significantly. The high-impedance state and  
increased drive provide the capability to drive bus  
lines in bus-organized systems without need for  
interface or pullup components.  
9 10 11 12 13  
OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered  
while the outputs are in the high-impedance state.

description/ordering information (continued)  
To ensure the high-impedance state during power up or power down, OE should be tied to V  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

stg  
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.  
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.  
2. The package thermal impedance is calculated in accordance with JESD 51-7.

TBD: The Pb-Free/Green conversion plan has not been defined.  
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements  
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered  
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and  
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS  
compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame  
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)  
(3)  
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder  
temperature.

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 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.  
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.
