5962-8515513RA

Overview

The Texas Instruments 5962-8515513RA is a military-grade, octal buffer and line driver featuring three-state outputs. It belongs to the SN54HCT244 family, utilizing HCT CMOS technology for compatibility with standard TTL logic levels. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting in a CFP-40 package. It is designed for high-speed data bus applications requiring isolation or signal driving capabilities in harsh environments.

Feature Summary

• Octal configuration with independent output enable controls
• Three-state outputs for efficient bus sharing
• HCT input compatibility with standard 5V TTL systems
• Military qualification (-55°C to +125°C operating temperature)

Applications

• High-speed data bus isolation in military avionics
• Memory address and data bus drivers
• Clock distribution networks
• Signal buffering in harsh environment computing systems

Procurement Notes

This component carries a DLA (Defense Logistics Agency) 5962 prefix, indicating it is procured under government military specifications. Availability is typically restricted to authorized defense contractors or entities with appropriate security clearances. Standard commercial distributors may not list this part; procurement usually requires direct engagement with Texas Instruments defense sales channels or certified government suppliers. Verify current production status and lead times directly with the manufacturer.

Selection Notes

Select the 5962-8515513RA when military reliability and HCT logic compatibility are required for octal buffering. Ensure the design accommodates the CFP-40 ceramic package dimensions and thermal requirements. Compare against commercial equivalents like the SN54HCT244 if environmental constraints allow, noting that the 5962 version offers enhanced screening and traceability for defense applications.

Part Context

The 5962-8515513RA is the military-grade variant of the SN54HCT244 octal buffer. The '5962' prefix denotes a DLA catalog number, while 'RA' specifies the ceramic flat package with gold contact leads. This part is part of TI's broader portfolio of radiation-hardened and high-reliability digital logic components designed for long-term availability in defense sectors.

Replacement Considerations

Direct pin-compatible replacements include other SN54HCT244 variants from Texas Instruments or equivalent manufacturers offering military-grade octal buffers with three-state outputs. Verify voltage levels, package dimensions, and speed characteristics before substitution.
