Frequently Asked Questions
What are the primary applications for this flip-flop?
These devices are suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.
How is the high-impedance state maintained during power cycling?
To ensure the high-Z state upon startup or shutdown, OE should be tied to V using a pullup resistor.
What are the limitations for use in critical industries like automotive applications?
The product must be specifically designated by TI as compliant with requirements (e.g., ISO/TS 16949), otherwise, use is solely at your risk.
