JM38510/65705BSA

Overview

The JM38510/65705BSA is a military-grade octal buffer and line driver manufactured by Texas Instruments. It features eight channels with three-state outputs, designed for high-reliability applications. The device operates within a voltage range of 2 V to 6 V and supports bidirectional data transfer. It is housed in a 20-pin Ceramic Flat Pack (CFP) package, suitable for harsh environments. The component functions as a bus transceiver or buffer, providing signal isolation and drive capability. It is rated for an operating temperature range from -55 °C to 125 °C, ensuring stability under extreme thermal conditions.

Feature Summary

• Military-grade reliability with ceramic flat pack packaging
• Octal configuration with three-state output control
• Wide supply voltage operation from 2 V to 6 V
• Bidirectional data transmission capability

Applications

• Military aerospace communication systems
• Harsh environment data bus interfaces
• High-reliability industrial control networks
• Spacecraft telemetry and command subsystems

Procurement Notes

Verify the specific suffix 'BSA' confirms the ceramic flat pack variant and military qualification level. Ensure the order specifies the correct temperature grade and package style. Confirm compliance with relevant military standards such as MIL-PRF-38534 if required for your system integration. Check for any specific marking or traceability requirements mandated by your procurement contract.

Selection Notes

Select this component when high noise immunity and bidirectional buffering are required in space-constrained military designs. The CFP package offers robust mechanical stability compared to plastic alternatives. Consider the 2 V to 6 V input compatibility for mixed-voltage logic interfaces. Evaluate the three-state output feature for efficient bus sharing in complex digital architectures.

Part Context

This part belongs to the SN54 series of military logic devices, which are characterized by extended temperature ranges and rigorous testing protocols. It serves as a specialized version of standard commercial buffers, adapted for defense and aerospace use. The designation indicates its origin from Texas Instruments' military product line, ensuring adherence to strict quality and performance standards defined by government specifications.

Replacement Considerations

Direct substitutes include other military-grade octal buffers with identical pinouts and electrical characteristics. Verify that alternative parts meet the same MIL-PRF-38534 qualifications. Ensure the replacement maintains the 20-pin CFP form factor and 3-state output functionality. Cross-reference datasheets for propagation delay and quiescent current to guarantee system compatibility.
