5962-9221305MRA

Overview

The Texas Instruments 5962-9221305MRA is a military-grade, fast CMOS octal buffer and line driver. It operates within an extended temperature range of -55°C to +125°C and features true TTL input and output compatibility with typical high-level output voltage of 3.3V and low-level output voltage of 0.3V. The device provides high drive capability with outputs capable of sourcing -15mA and sinking 64mA. It meets or exceeds JEDEC standard 18 specifications and complies with MIL-STD-883, Class B requirements.

Feature Summary

• Octal configuration designed for memory, address, clock drivers, and bus-oriented transmitter/receiver applications to improve board density.
• Power-off disable feature enables live insertion by preventing interference during system hot-swapping.
• Military compliance ensures reliability in harsh environments through adherence to MIL-STD-883, Class B standards.

Applications

• Memory address drivers
• Clock signal distribution
• Bus-oriented data transmission

Procurement Notes

Verify the specific suffix MRA against official Texas Instruments documentation to confirm package type and qualification level. Ensure the component matches the required MIL-STD-883 Class B specification for your application. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and authenticity before procurement.

Selection Notes

Select this component when high-density octal buffering is required for TTL-compatible systems operating in extreme temperatures. The high drive current supports long bus lines, while the power-off disable feature simplifies system integration for live insertion scenarios. Verify that the package style aligns with your PCB layout constraints.

Part Context

This part belongs to the Fast CMOS (FCT) family, which offers improved performance over standard CMOS logic. It serves as a military version of commercial octal buffers, providing enhanced drive strength and noise immunity suitable for demanding industrial and aerospace environments where standard commercial parts may not suffice.

Replacement Considerations

The datasheet identifies the IDT 54FCT240T as an equivalent commercial part. For direct military-grade replacements, consult Texas Instruments for updated equivalents within the 5962 series. Verify pinout and electrical characteristics match exactly before substituting.
