description  
These 10-bit edge-triggered D-type flip-flops  
feature 3-state outputs designed specifically for  
driving highly capacitive or relatively low-impedance loads. These devices are particularly suitable for  
implementing wider buffer registers, I/O ports, bidirectional bus drivers with parity, and working registers.  
On the positive transition of the clock (CLK) input, the Q outputs are true to the data (D) input.  
A buffered output-enable (OE) input can place the ten outputs in either a normal logic state (high or low logic  
levels) or a high-impedance state. The outputs also are in the high-impedance state during power-up and  
power-down conditions. The outputs remain in the high-impedance state while the device is powered down. 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 without interface or pullup components.  
OE does not affect the internal operation of the flip-flops. Old data can be retained or new data can be entered  
while the outputs are in the high-impedance state.  
The SN54ALS29821 is characterized for operation over the full military temperature range of 55°C to 125°C.  
The SN74ALS29821 is characterized for operation from 0°C to 70°C.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability  
information and additional product content details.  
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.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.

(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest  
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and  
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale  
supplied at the time of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license 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 significant portions 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. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of  
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
