Frequently Asked Questions
What is the operating voltage range?
4.5-V to 5.5-V VCC Operation.
How do I ensure outputs are high-impedance during power cycling?
Tie OE to VCC via a pullup resistor during power up or power down.
What are the typical applications?
Implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
What does the output enable (OE) pin do?
Places outputs in normal logic state or high-impedance state; it does not affect internal flip-flop operations.
