74HCT534D,652

Overview

The 74HCT534D,652 is a 9-bit D-type flip-flop with inverting outputs and tri-state control, manufactured by NXP USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 24 ns at 4.5 V with a 50 pF load. It is housed in a 20-SOIC package (SOP16,.25) and supports surface-mount installation. The component complies with RoHS standards and has a moisture sensitivity level of 1.

Feature Summary

• Contains nine D-type flip-flops with inverting outputs
• Includes a tri-state output control function for bus driving
• Operates with high noise immunity compatible with TTL inputs

Applications

• Parallel data storage in digital systems
• Bus interface circuits requiring tri-state isolation
• Shift register configurations for data serialization

Procurement Notes

Verify the specific ordering code suffix to ensure compatibility with required packaging formats. Confirm that the procurement source provides official documentation from NXP or Nexperia to guarantee authenticity. Check for any recent product change notices regarding manufacturing site transfers or marking updates before finalizing orders.

Selection Notes

Select this component when a 9-bit parallel load capability with tri-state outputs is required. Ensure the system logic levels are compatible with HCT standards. Verify that the SOIC package footprint matches the PCB design constraints. Consider thermal dissipation requirements if multiple devices are used in close proximity on the same board.

Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices. It is functionally similar to other 9-bit latch variants but specifically includes inverting outputs. The 'D' suffix indicates the SOP package type, while ',652' denotes the standard tape and reel packaging configuration provided by the manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official NXP/Nexperia replacement guides for cross-reference information.
