Frequently Asked Questions
What is the primary function of the high-impedance state?
The high-impedance state ensures outputs neither load nor drive the bus lines significantly, allowing for bus-organized systems without extra components.
How must I set up the OE pin during power cycling?
To keep the high-impedance state when powering up or down, the OE input should be tied to Vcc through a pullup resistor.
What are these flip-flops best used for in circuit design?
They are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
What is the maximum operating voltage range for this device?
The supply voltage range (Vcc) for the SN74AC374 is −0.5 V to 7 V, with input voltages accepting up to 6 V.
