SN54BCT29841 . . . FK PACKAGE
(TOP VIEW)
These 10-bit bus-interface latches feature 3-state
outputs designed specifically for driving highly
capacitive or relatively low-impedance loads.
They are particularly suitable for implementing
wider buffer registers, I/O ports, bidirectional bus
drivers with parity, and working registers.

The ten latches of the ′BCT29841 are transparent
D-type latches. When the latch-enable (LE) input
is high, the Q outputs will follow the data (D) inputs.
When LE is taken low, the Q outputs are latched
at the levels that were set up at the D inputs.

A buffered output-enable (OE) input can be used
to place the nine outputs in either a normal logic
state (high or low level) or a 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 without need for
interface or pullup components.
NC − No internal connection
The output enable (OE) does not affect the internal operation of the latches. Old data can be retained or new
data can be entered while the outputs are in the high-impedance state.
The SN54BCT29841 is characterized for operation over the full military temperature range of −55°C to 125°C.
The SN74BCT29841 is characterized for operation from 0°C to 70°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. This is a stress rating only, and
functional operation of the device at these or any other conditions beyond those indicated in the “recommended operating conditions” section of
this specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

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,

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
