Product details

What this 74AC flip-flop does on the board

The SN74AC564DW: It takes in eight bits on the D inputs and latches them to the Q outputs in inverted form through a tri-state bus — the kind of buffer you reach for when the data bus needs to float on command and the logic polarity flips between stages.

Clock speed, propagation delay, and drive — what the numbers mean for your timing budget

95 MHz clock frequency sets the maximum toggle rate — above that the setup/hold window closes and the output stops tracking the input reliably. Output drive is 24 mA source and sink — enough to light a small LED or drive a few CMOS inputs without a buffer, but not enough for a relay coil or a long twisted-pair run. Quiescent current sits at 4 µA, so the chip draws almost nothing when the clock is stopped and the outputs are static. Input capacitance is 4.5 pF per pin — factor that into the clock tree loading if you are running a high-speed bus with multiple loads on the same trace.

Frequently asked questions

How does SN74AC564DW compare to SN74LVC574APWT?

The SN74AC564DW has inverted tri-state outputs and a wider supply range. They are not pin-compatible drop-in replacements — the output polarity difference alone means a board spin if the downstream logic expects inverted data.

What compliance documentation does Texas Instruments provide for SN74AC564DW?

Texas Instruments provides ROHS3 compliance for the SN74AC564DW. The part is Active and carries the standard TI datasheet with electrical characteristics, timing diagrams, and package drawing.
