Flip Flops FAQ

What is the input logic level compatibility of the SN74ACT564DW?

The device features TTL-compatible inputs, allowing it to interface directly with standard TTL logic outputs.

How does the three-state output function operate on this IC?

The three-state outputs allow the flip-flops to be disconnected from the bus when not selected, preventing signal contention in multi-device systems.
