5962-9583101QSA

Overview

The Texas Instruments 5962-9583101QSA is a military-grade, octal transparent D-type latch featuring three-state outputs. It operates on a single 3.3-V supply voltage and supports mixed-mode signal operation, allowing 5-V input and output voltages while maintaining a 3.3-V VCC. The device is housed in a 20-CFP package and is rated for an extended operating temperature range from -55°C to +125°C.

Feature Summary

• Supports mixed-mode signal operation with 5-V I/O levels compatible with 3.3-V power supplies
• Features active bus-hold circuitry to maintain valid logic levels on unused or floating inputs
• Provides three-state outputs for effective bus line driving applications

Applications

• Military electronic systems requiring high reliability
• Mixed-voltage digital logic interfaces
• Data storage and buffering in aerospace environments

Procurement Notes

Verify the specific suffix QSA against your design requirements to ensure compatibility with military qualification standards. Confirm that the 20-CFP package matches your PCB footprint. Ensure your system design accounts for the mixed-mode voltage capabilities when interfacing with 5-V logic devices. Always consult the official datasheet for detailed electrical characteristics and handling instructions before integration.

Selection Notes

Select this component when designing systems that require octal latching with three-state outputs in harsh environments. It is suitable for applications needing interface between 3.3-V and 5-V logic domains without external level shifters. Consider the CFP package constraints and thermal management requirements for high-temperature operation up to 125°C.

Part Context

This part belongs to the SN54ABT series of high-speed CMOS logic devices manufactured by Texas Instruments. The 5962 prefix indicates it is a military-grade version produced under government specifications. It is designed for high-performance digital applications requiring robust noise immunity and wide operating temperature ranges typical of defense and aerospace sectors.

Replacement Considerations

Check for direct equivalents within the SN54ABT family. Verify pinout and electrical specifications against any alternative octal latches. Ensure substitute parts meet the same military temperature and radiation hardness requirements if applicable.
