These 8-bit flip-flops with 3-state outputs are

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 are edge-triggered D-type

flip-flops. On the positive transition of the clock

(CLK), the Q outputs are set to the complement of

the logic levels set up at the data (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 a high-impedance state. In the high-impedance state, the outputs neither load nor drive

thebuslinessignificantly. Thehigh-impedancestateandincreaseddriveprovidethecapabilitytodrivebuslines

without need for interface or pullup components.

OE does not affect the internal operations of the flip-flop. Previously stored data can be retained or new data

can be entered while the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54ABT534 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74ABT534A is characterized for operation from –40°C to 85°C.
