5962-9318801MRA

Overview

The Texas Instruments 5962-9318801MRA is an octal buffer and line driver featuring three-state outputs, designed for military-grade applications. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a wide operating temperature range from -55°C to +125°C. The device utilizes a 20-pin Ceramic Dual In-Line Package (CDIP) with J-leads. Key electrical characteristics include a propagation delay of 18 ns at 5 V, a high-level output current of -29 mA, and a low-level output current of 48 mA. It belongs to the SN54128 logic series and employs bipolar technology.

Feature Summary

• Provides eight buffered channels with independent three-state control for bus-oriented architectures.
• Engineered for harsh environments with extended temperature ratings suitable for military specifications.
• Delivers high drive capability through robust bipolar output stages.

Applications

• Military communication systems requiring reliable signal buffering
• High-reliability data acquisition modules
• Aerospace control units

Procurement Notes

Verify that the specific ordering suffix matches the required package variant and qualification level. Confirm compliance with MIL-PRF-38534 or equivalent standards if applicable. Ensure the supplier provides traceability documentation for military-grade components. Check for any specific handling requirements due to the ceramic package construction.

Selection Notes

Select this component when eight-channel buffering with three-state isolation is required in extreme temperature conditions. Consider the bipolar technology's drive strength compared to CMOS alternatives. Verify pin compatibility with existing PCB layouts designed for 20-lead CDIP packages. Evaluate power dissipation limits under maximum load conditions.

Part Context

This part is part of the SN54xx series, which denotes military-grade performance levels. It serves as a digital logic interface component, translating signals between different circuit blocks while providing isolation via three-state outputs. The ceramic package ensures hermetic sealing for long-term reliability in demanding environments.

Replacement Considerations

Direct substitutes may include other SN54128 variants with compatible packaging. Verify pinout and electrical specifications before substitution. Cross-reference with other manufacturers' military-grade octal buffers if TI availability is restricted.
