Flip Flops FAQ

What is the logic polarity of the SN74HC574ANS?

The device exhibits non-inverting logic polarity, meaning the output state follows the input state upon clock triggering.

How does the three-state output benefit bus applications?

The three-state outputs allow the device to disconnect from the bus when not enabled, preventing signal contention with other connected devices.
