description

This 8-bit flip-flop features 3-state outputs designedspecifically for driving highly-capacitive or relativelylow-impedance loads. It is particularly suitable for implementingbuffer registers, I/O ports, bidirectional bus drivers, and workingregisters.

The eight flip-flops of the 74ACT11374 are edge-triggered D-typeflip-flops. On the positive transition of the clock (CLK) input, theQ outputs are set to the logic levels set up at the data (D) inputs.

An output-enable ()input can be used to place the eight outputs in either a normal logicstate (high or low logic levels) or a high-impedance state. In thehigh-impedance state, the outputs neither load nor drive the buslines significantly. The high-impedance third state provides thecapability to drive bus lines in a bus-organized system without needfor interface or pullup components.

does not affectthe internal operation of the flip-flops. Old data can be retained ornew data can be entered while the outputs are in the high-impedancestate.

The 74ACT11374 is characterized for operation from -40°C to85°C.
