This 8-bit flip-flop features 3-state outputs 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 (
)
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.
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 -40°C to 85°C.
