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

The eight flip-flops of the ′F534A are
edge-triggered D-type flip-flops. On the positive
transition of the clock, the Q outputs are set to the
complement of the logic states that were set up at
the data (D) inputs. The ′F534A is equivalent to the
′F374 except for having inverted outputs.

A buffered output enable (OE ) control input can
be used to place the eight outputs in either a
normal logic state (high or low logic levels) 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.

The output enable (OE) does not affect the internal operations of the flip-flops. Old data can be retained or new
data can be entered while the outputs are off.
The SN54F534A is characterized for operation over the full military temperature range of −55°C to 125°C. The
SN74F534A is characterized for operation from 0°C to 70°C.

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,

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
