5962-9758601QRA

Overview

The Texas Instruments 5962-9758601QRA is a military-grade SN54F244 octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to 125°C. The device utilizes a 20-pin CDIP (J) package and draws a maximum supply current of 90,000 µA. This component is designed for high-reliability applications requiring robust signal buffering in harsh environments.

Feature Summary

• Military-rated reliability for extreme environmental conditions
• Octal configuration with independent control lines
• Three-state output capability for bus-oriented systems

Applications

• Military communication systems
• Avionics data buses
• High-reliability industrial control interfaces

Procurement Notes

Verify the specific suffix 'QRA' against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Confirm availability status as lifetime buy or active production, as discontinuation notices may apply to certain variants. Ensure the CDIP-20 package compatibility with your PCB footprint before finalizing procurement orders.

Selection Notes

Select this component when designing systems that require strict MIL-STD compliance and wide temperature operation. The SN54 series designation indicates military qualification compared to commercial SN74 equivalents. Consider the bipolar technology characteristics and power consumption profile relative to CMOS alternatives for your specific interface needs.

Part Context

This part belongs to the SN54F244 family of octal buffers/drivers. The 5962 prefix denotes a Department of Defense microcircuit purchase description, indicating it is a qualified military version of the commercial SN54F244. The QRA suffix specifies the package type and thermal grade.

Replacement Considerations

Direct replacements include other SN54F244 variants with compatible military ratings. Verify package equivalence for CDIP-20 configurations. Cross-reference with SN54LS244 if lower power consumption is required, noting potential speed differences.
