This 8-bit flip-flop features 3-state outputs of the 74ACT11374 designed specifically for driving highly-capacitive or relatively low-impedance loads. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

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

An 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 the bus lines significantly. The high-impedance third state provides the capability to drive bus lines in a bus-organized system without need for 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 74ACT11374 is characterized for operation from 40to 85.
