5962-9450201QXA

Overview

The Texas Instruments 5962-9450201QXA is a registered bus transceiver belonging to the AC logic family. It supports serial-to-parallel and parallel-to-serial data transfer modes within an 8-stage configuration. The device operates with a supply voltage range of 1.5 V to 5.5 V and features bidirectional data direction control. It utilizes rising-edge triggering for data capture and includes asynchronous reset functionality. Designed for surface-mount installation, it is housed in a 20-pin SOIC package and is qualified for operation across an extended temperature range from -55 °C to +125 °C.

Feature Summary

• Supports bidirectional data transfer between serial and parallel interfaces
• Features asynchronous reset capability for immediate state clearing
• Utilizes rising-edge triggered registration for reliable data synchronization

Applications

• High-speed data buffering in communication systems
• Parallel-to-serial conversion in digital signal processing chains
• Interface bridging between microprocessors and peripheral devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to military-grade part number designation. Confirm RoHS compliance status as historical records may vary. Ensure storage conditions meet moisture sensitivity level requirements for leaded packages. Validate pinout compatibility with target PCB layout before integration. Request batch-specific documentation to confirm manufacturing origin and traceability.

Selection Notes

Select this component when bidirectional data flow between serial and parallel domains is required. The wide supply voltage range accommodates various logic families. The extended temperature range suits harsh environmental applications. Consider the 20-pin SOIC package constraints for board space. Verify that the asynchronous reset feature aligns with system initialization requirements.

Part Context

This part belongs to Texas Instruments' AC logic series, known for high-speed performance. The 5962 prefix indicates a military-grade or high-reliability variant manufactured under specific quality standards. It serves as a registered buffer/transceiver, distinct from standard unregistered logic gates. The AC series offers improved speed-power product compared to older HC or HCT families.

Replacement Considerations

Direct replacements include other AC logic registered bus transceivers with compatible pinouts and electrical characteristics. Verify equivalent parts maintain the same 1.5 V to 5.5 V operating range and bidirectional functionality. Check for identical package dimensions and thermal properties. Ensure substitute components meet the same reliability standards if used in critical applications.
