• Engineered for low-voltage operation suitable for portable and battery-powered systems
• Features high noise immunity and low power consumption characteristics typical of VCX technology

Applications

• Bus interface circuits requiring data latching
• Portable electronic devices with limited power budgets
• High-density memory address registers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to the component's obsolete status. Confirm package integrity and pin alignment against the 48-TSSOP specification before integration. Ensure that the specific tape and reel packaging matches design requirements for automated assembly processes. Cross-reference datasheet revisions to confirm electrical parameters remain consistent with original design specifications.

Selection Notes

Select this component when designing systems requiring 16-bit parallel data storage with tri-state bus capabilities under low voltage conditions. Consider the -55°C to +125°C industrial temperature range for robust environmental performance. Evaluate the 1.8V to 3.6V supply compatibility with existing system rails. Assess the 48-TSSOP footprint constraints against available PCB real estate for surface-mount implementation.

Part Context

This part belongs to the 74VCX family of low-voltage CMOS logic devices, optimized for high-speed and low-power applications. It serves as a successor or alternative to standard 74LVX series components where higher density and specific bus interface features are required. The TTR suffix indicates the tape and reel packaging configuration for automated manufacturing.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should evaluate equivalent 16-bit D-type flip-flops from other manufacturers or newer generations within the same logic family that offer compatible pinouts and electrical characteristics.
