5962-8683901SA

Overview

The Texas Instruments 5962-8683901SA is a military-grade octal buffer and line driver belonging to the SN54ALS244C series. It features eight independent buffers with three-state outputs, designed for high-speed digital applications. The device operates within an extended temperature range of -55°C to 125°C and utilizes TTL input and output logic levels. Packaged in a CDFP20 ceramic flat package, it supports bus-oriented systems requiring low power consumption and high noise immunity characteristic of ALS technology.

Feature Summary

• Provides eight independent buffering channels with true output polarity
• Features three-state outputs for effective bus line driving and isolation
• Constructed using Advanced Low-Power Schottky (ALS) technology for speed and efficiency
• Rated for military-grade reliability across extreme temperature environments

Applications

• Military communication systems requiring robust signal buffering
• High-reliability computer memory bus architectures
• Industrial control systems operating in harsh thermal conditions
• Aerospace data acquisition and processing units

Procurement Notes

Verify the specific suffix 'SA' confirms the military grade and ceramic package variant. Ensure compatibility with existing board layouts for the CDFP20 footprint. Confirm that the TTL logic levels align with the system's voltage requirements. Check for any specific handling instructions regarding ceramic packages. Validate that the component meets all necessary environmental certifications for the intended deployment.

Selection Notes

Select this component when eight-channel buffering with three-state capability is required in demanding environments. Consider the ALS technology benefits for balancing speed and power dissipation. Evaluate the CDFP20 package constraints against available PCB space. Compare performance metrics against standard commercial variants if cost is a secondary factor to reliability. Ensure the TTL interface matches the source and destination logic families.

Part Context

This part is a militarized version of the SN54ALS244C octal buffer. It falls under Texas Instruments' legacy logic family, specifically the ALS series known for improved performance over standard LS logic. The 5962 prefix indicates it is a direct chip carrier product often sourced through specialized defense supply chains rather than general consumer distributors.

Replacement Considerations

Direct replacements include other SN54ALS244 variants with compatible packaging. Verify pinout compatibility before substituting with similar octal buffers from other manufacturers. Ensure the replacement maintains the three-state output functionality and TTL compatibility.
