FAQ

What is the logic polarity of the CY74FCT541TQCT?

The device features non-inverting logic, meaning the output state follows the input state directly.

How does the three-state output function operate?

The outputs enter a high-impedance state when the enable input is deactivated, effectively disconnecting them from the circuit.
