5962-9450901QKA

Overview

The Texas Instruments 5962-9450901QKA is a military-grade buffer and line driver belonging to the SN54ABT827 series. It features ten non-inverting channels with TTL-compatible CMOS inputs and three-state outputs, housed in a 24-pin Ceramic Flat Pack (CFP) package. The device operates on a supply voltage range of 4.5 V to 5.5 V and supports an extended industrial temperature range from -55°C to +125°C. Key electrical specifications include a propagation delay of 2.6 ns at 5 V with a 50 pF load, a high-level output current of 32 mA, and a low-level output current of 64 mA.

Feature Summary

• Features ten non-inverting buffering channels with TTL-compatible CMOS inputs for versatile logic interfacing
• Provides three-state outputs to facilitate bus-oriented architectures and system isolation
• Engineered for military applications with qualified performance across extreme temperature environments

Applications

• Military communication systems requiring robust signal buffering
• Bus-oriented digital architectures utilizing three-state control
• High-speed data transmission lines demanding low propagation delay

Procurement Notes

Verify that the specific QDA or QKA suffix corresponds to the required military qualification level and lead time constraints. Confirm package integrity upon receipt, as ceramic flat packs are sensitive to mechanical stress during handling. Ensure compatibility with existing board layouts regarding pin assignments and thermal dissipation requirements for the CFP-24 form factor.

Selection Notes

Select this component when ten buffered channels with three-state capability are required in a single package. The ABT technology offers faster switching speeds compared to standard bipolar TTL alternatives. Consider the CFP-24 package dimensions and mounting style against available PCB real estate and assembly capabilities.

Part Context

This part is a militarized version of the commercial SN54ABT827 buffer. It falls under the broader category of high-speed BiCMOS logic devices designed for demanding environments. The 5962 prefix indicates it is a direct-read MIL-SPEC part manufactured by Texas Instruments.

Replacement Considerations

Direct substitutes include other SN54ABT827 variants with different suffixes for packaging or qualification levels. Verify pinout compatibility before replacing with generic equivalents.
