Procurement Notes

Verify the specific ordering suffix and marking code (HCT574EP) against official Texas Instruments documentation to ensure authenticity. Confirm that the procurement channel provides traceability for military-enhanced products. Check for any updated replacement part numbers or availability notices on the manufacturer's website before finalizing orders, as supply chain statuses for specialized components may change.

Selection Notes

Select this component when a high-reliability, 8-bit D-type flip-flop is required for military or industrial applications. Ensure the design environment supports the specified 4.5V to 5.5V supply voltage and -40°C to +125°C temperature range. Verify compatibility with TTL input levels and the need for non-inverting outputs. Consider the 20-TSSOP package dimensions for PCB layout constraints.

Part Context

This part belongs to Texas Instruments' portfolio of high-reliability electronic components designed for mission-critical applications. It represents a specialized variant of standard logic devices, enhanced to meet rigorous military standards for performance and longevity. The V62 prefix indicates its classification within the company's military and space-grade product lines, distinct from commercial offerings.

Replacement Considerations

Check the official Texas Instruments product page for any listed newer substitutes or direct replacements. Verify if alternative parts maintain the same military-enhanced rating, pinout, and electrical specifications. Consult distributor catalogs for cross-reference information, ensuring any substitute matches the 20-TSSOP package and 8-bit D-type functionality.
