5962-9223801MRA

Overview

The 5962-9223801MRA is a Fast CMOS octal transparent latch manufactured by Renesas Electronics Corporation. It features eight independent D-type transparent latches with tri-state outputs, designed for high-speed data storage and bus holding applications. The device operates within a supply voltage range of 4.5V to 5.5V, ensuring compatibility with standard 5V logic systems. Packaged in a 20-CDIP (Ceramic Dual In-Line Package) with dimensions of 25.4mm x 7.62mm x 2.9mm, it supports robust industrial environments. This component is classified as obsolete but remains documented for legacy system maintenance.

Feature Summary

• Octal configuration providing eight independent transparent latches for parallel data handling
• Tri-state output capability enabling efficient bus sharing and isolation
• Fast CMOS technology optimized for high-speed switching performance
• D-type transparent latch architecture for direct data path control

Applications

• Parallel data bus holding in legacy computer systems
• Interface buffering between microprocessors and peripheral devices
• Data storage in industrial control panels requiring 5V logic compatibility

Procurement Notes

Verify component status carefully as this part is officially listed as obsolete. Confirm availability through authorized distributors or surplus suppliers. Ensure the 20-CDIP package matches your existing PCB footprint. Check for RoHS compliance markings if required by current assembly standards. Validate pinout compatibility before integration into new designs.

Selection Notes

Select this component only for maintaining existing hardware using 5V logic families. Consider modern equivalents if designing new equipment due to obsolete status. Evaluate mechanical fit within the 20-CDIP ceramic package constraints. Assess thermal requirements for industrial operating conditions. Verify signal integrity needs against Fast CMOS specifications.

Part Context

This part belongs to Renesas' legacy fast CMOS logic family, specifically designed for high-density data storage applications. The 5962 prefix indicates military-grade or high-reliability variant sourcing. As an octal latch, it serves critical roles in digital systems requiring parallel data retention. The CDIP package offers superior environmental protection compared to plastic variants.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific obsolete model. Engineers should evaluate generic octal latches with matching voltage and package specifications. Cross-reference pinouts carefully when selecting alternative components from other manufacturers.
