Procurement Notes

Verify the specific suffix J against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the design supports the required 4.5V to 5.5V supply rail and 20-TSSOP footprint. Confirm AEC-Q100 compliance requirements match project needs before finalizing procurement orders.

Selection Notes

Select this component when designing for automotive applications requiring 8-bit parallel data storage with TTL-compatible inputs. Consider the 36 MHz speed limit and 30ns delay for timing constraints. Compare against 74HC or 74AH variants if lower voltage operation or higher speed is required instead of automotive grade.
