5962-8685701RA

Overview

The Texas Instruments 5962-8685701RA is a military-grade, radiation-hardened integrated circuit belonging to the CD54HCT688 series. It functions as an 8-bit identity and magnitude comparator with enable functionality. The device utilizes CMOS technology and features TTL-compatible inputs. It is housed in a 20-pin Ceramic Dual In-Line Package (CDIP-J). The component operates within a supply voltage range of 4.5 V to 5.5 V. It supports a wide operating temperature range from -55°C to +125°C, ensuring reliability in harsh environments.

Feature Summary

• Provides 8-bit identity and magnitude comparison capabilities
• Features TTL-compatible logic levels for interface flexibility
• Includes enable control for output management
• Designed for high-reliability military and aerospace applications

Applications

• Military avionics systems requiring radiation hardness
• Aerospace data processing units
• High-reliability industrial control comparators
• Spacecraft electronic subsystems

Procurement Notes

This part number represents a specific military-grade variant manufactured by Texas Instruments. Verify that the required package style matches the CDIP-J specification. Confirm that the application environment necessitates the radiation-hardened characteristics provided by this series. Ensure compatibility with the specified 4.5 V to 5.5 V power supply rails before integration into the design.

Selection Notes

Select this component when standard commercial logic devices are insufficient for extreme environmental conditions. It is appropriate for designs requiring radiation tolerance and extended temperature operation. Consider the CDIP-J package constraints regarding board space and mounting requirements. Evaluate if the 8-bit comparison width meets the system's data processing needs without requiring additional external logic components.

Part Context

The 5962-8685701RA belongs to the broader family of CD54HCT688 devices. These parts are standardized under MIL-PRF-38534 specifications for high-reliability mixed-signal integrated circuits. The prefix indicates a specific quality level and testing regimen distinct from commercial counterparts. This classification ensures consistent performance across production lots for critical defense and space missions.

Replacement Considerations

Direct substitutes include other variants within the CD54HCT688 family that share identical electrical specifications and pinouts. Cross-reference alternative manufacturers offering MIL-PRF-38534 qualified equivalents. Verify that any replacement maintains the same radiation hardness assurance levels and thermal ratings.
