5962-9457702QLA

Overview

The Texas Instruments 5962-9457702QLA is a military-grade SN54ABT646A octal bus transceiver and register. It features high-speed operation with propagation delays of up to 100 ns, supporting 5V logic levels. The device provides high-drive outputs capable of -32 mA IOH and 64 mA IOL, ensuring robust signal integrity in demanding environments. It operates within an extended temperature range of -55°C to +125°C and includes Ioff support for partial-power-down mode. Housed in a 24-pin CDIP package, it is designed for reliable performance in aerospace and defense applications requiring strict thermal and electrical stability.

Feature Summary

• Octal bus transceiver architecture with integrated register functionality
• High-drive output capability for enhanced signal integrity
• Supports partial-power-down mode via Ioff feature
• Extended military-grade temperature range for harsh environments

Applications

• Aerospace and defense data transmission systems
• Military-grade computing and communication interfaces
• High-reliability industrial control networks

Procurement Notes

Verify the specific revision level and lot traceability documentation upon procurement. Ensure that the CDIP-24 package matches your PCB footprint requirements. Confirm compliance with export control regulations as this component may require additional licensing for international shipment. Validate that the supplier provides authentic TI military-grade parts with full chain-of-custody records.

Selection Notes

Select this component when designing systems requiring octal bidirectional data transfer with registered storage capabilities. It is suitable for applications needing high drive strength and low output ground bounce under 5V operation. Consider its military temperature rating if the environment exceeds standard commercial limits. Ensure compatibility with ABT logic families for seamless integration into existing high-speed digital designs.

Part Context

This part belongs to the SN54 series, which denotes military-grade reliability standards compared to the commercial SN74 series. It is functionally equivalent to the SN54ABT646A but manufactured to stricter quality controls. The 5962 prefix indicates it is a direct buy or military-specific variant managed through authorized distributors like Rochester Electronics.

Replacement Considerations

The SN54ABT646A is the commercial counterpart. Verify pinout compatibility before substitution. Ensure the replacement meets the required -55°C to +125°C operating temperature range. Check for any differences in output drive characteristics or power-down current specifications between the military and commercial versions.
