M38510/10403BEA

Overview

M38510/10403BEA is a dual differential line driver manufactured by Texas Instruments, functioning as the military-grade equivalent of the SN55114. It operates on a single 5-V supply and provides high-current outputs designed for driving balanced lines such as twisted pairs at normal impedances without excessive power dissipation. The device features TTL-compatible output levels and includes short-circuit protection. It supports triple inputs per channel and incorporates clamp diodes at both inputs and outputs to handle transient voltages.

Feature Summary

• Provides differential output signals with high-current capability suitable for driving balanced transmission lines like twisted pairs.
• Features selectable output stages including open-collector, open-emitter, or totem-pole configurations for flexible logic interfacing.
• Includes built-in short-circuit protection and input/output clamp diodes to enhance reliability during abnormal voltage conditions.

Applications

• Differential data transmission over balanced lines
• TTL logic expansion and phase splitting
• Interfacing with differential line receivers

Procurement Notes

Verify that the component matches the specific M38510/10403BEA part number to ensure it meets the required military specifications. Confirm the package type corresponds to the CDIP (J) format as listed in the official documentation. Check for any specific quality assurance certifications or screening levels mandated by your procurement standards before finalizing the order.

Selection Notes

Select this component when a ruggedized, military-specification differential line driver is required for harsh environments. It is appropriate for designs needing high-current drive capabilities on balanced lines while maintaining TTL compatibility. Consider its interchangeability with other qualified versions if supply constraints exist, ensuring all electrical parameters align with the system requirements.

Part Context

This part belongs to the SN55114 family of dual differential line drivers. It is specifically designated under the M38510 series, indicating it is a QML-certified product intended for military and defense applications. It serves as a direct replacement for the standard SN55114 but adheres to stricter manufacturing and testing protocols defined by military standards.

Replacement Considerations

The SN55114J is a compatible alternative within the same family. Ensure that any substitute maintains the same military temperature range and package configuration to guarantee functional equivalence in existing designs.
