5962-89681012A

Overview

The Texas Instruments part number 5962-89681012A is a military-grade octal buffer and line driver belonging to the SN55ALS160 series. It features eight non-inverting inputs driving three-state outputs, designed for high-speed digital applications requiring IEEE-488 interface compatibility. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from -55 °C to +125 °C. Packaged in a CFP-20 ceramic flat package for surface mount installation, it draws a maximum operating supply current of 80 mA. This component provides robust signal buffering capabilities suitable for demanding environmental conditions.

Feature Summary

• Provides eight-channel non-inverting buffering with three-state output control for bus isolation
• Engineered for IEEE-488 interface applications ensuring reliable data transmission
• Utilizes ALS technology to achieve high-speed switching performance

Applications

• Military communication systems requiring ruggedized logic components
• IEEE-488 (GPIB) bus interface circuits
• High-reliability industrial data acquisition systems

Procurement Notes

Verify the specific suffix '2A' against official manufacturer documentation to confirm exact qualification standards and testing requirements. Ensure that the source document explicitly links this suffix to the SN55ALS160 functional specification. Confirm availability status directly with authorized distributors as supply may be restricted.

Selection Notes

Select this component when designing systems that require octal buffering with three-state outputs under extreme temperature conditions. Verify that the CFP-20 surface mount package aligns with the PCB layout constraints. Ensure the power supply can deliver the required 80 mA operating current while maintaining voltage stability within the 4.75 V to 5.25 V range.

Part Context

This part belongs to the SN55 series, which denotes military-grade reliability and extended temperature operation. It is functionally related to the commercial SN54ALS160 but meets stricter manufacturing and testing criteria defined by DoD specifications. The 5962 prefix indicates it is a direct chip buy item managed through government procurement channels.

Replacement Considerations

Direct substitutes include other military-qualified versions of the SN55ALS160. Verify pinout compatibility and electrical characteristics before substitution. Commercial equivalents like the SN54ALS160 do not meet the full temperature or reliability requirements.
