5962-86869012A

Overview

The Texas Instruments 5962-86869012A is a military-grade quadruple 1-of-2 data selector/multiplexer from the SN54ALS157A series. It features four independent multiplexers with common select lines, providing TTL-compatible inputs and true outputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -55°C to +125°C. Key electrical specifications include a maximum 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 is housed in a 20-lead CQCC (LCCC) package.

Feature Summary

• Military-grade reliability for extended temperature environments
• Quadruple 1-of-2 data selection architecture
• TTL-compatible input and output logic levels

Applications

• Military avionics signal routing
• High-reliability industrial control systems
• Data acquisition system multiplexing

Procurement Notes

This component is subject to restricted availability and may be produced under special factory orders. Verify current stock status and lead times directly with authorized distributors or Texas Instruments before design finalization. Ensure compliance with all military procurement standards and quality certifications required for your specific application environment.

Selection Notes

Select this part when requiring a quad multiplexer with ALS speed and drive strength in a military-rated package. Compare against standard commercial variants if environmental constraints are less stringent. Verify pinout compatibility with existing PCB layouts, as the LCCC package requires specific mounting considerations compared to smaller surface-mount options.

Part Context

This part belongs to the SN54 series, which denotes military-grade performance and wider temperature ranges compared to the SN74 commercial series. It is a militarized version of the SN54ALS157, offering faster switching speeds than standard LS logic while maintaining lower power consumption. The 5962 prefix indicates it is a direct chip carrier product manufactured under DoD specifications.

Replacement Considerations

Direct substitutes include other SN54ALS157 variants with different suffixes for packaging or temperature grades. Cross-reference with SN54LS157 for slower, higher-power alternatives if speed is not critical. Ensure any replacement maintains the same LCCC-20 footprint and military qualification requirements.
