JM38510/32301BCA

Overview

The JM38510/32301BCA is a military-grade LS series bus driver manufactured by Texas Instruments. It features four functional drivers with one-bit inputs and true outputs, housed in a 14-pin ceramic dual in-line package (CDIP). The device operates within a voltage range of 4.5 V to 5.5 V and supports an extended temperature range from -55 °C to 125 °C. It utilizes TTL input and output logic levels, ensuring compatibility with standard digital systems requiring robust signal transmission in harsh environments.

Feature Summary

• Military-grade construction using ceramic metal-sealed cofired packaging for enhanced durability
• LS series technology providing low power consumption while maintaining high-speed performance
• True output configuration compatible with standard TTL logic families

Applications

• Harsh environment digital signal buffering
• Military communication system interfaces
• Avionics data bus driving

Procurement Notes

Verify the specific suffix BCA indicates the correct commercial grade variant within the military specification line. Confirm the package type matches the required CDIP-14 footprint. Ensure the supplier provides traceability documentation consistent with aerospace or defense procurement standards. Check for lead time constraints associated with specialized ceramic packages.

Selection Notes

Select this component when a four-channel bus driver with LS speed characteristics is required for military applications. The CDIP package offers superior environmental resistance compared to plastic alternatives. Ensure the system design accommodates the 4.5 V to 5.5 V supply requirement. Verify that the true output polarity aligns with the downstream logic requirements.

Part Context

This part belongs to the JM38510 family, which defines military-standard integrated circuits. The 32301 designation specifically identifies the bus driver function within this hierarchy. Texas Instruments produces these components to meet rigorous reliability standards for defense and aerospace sectors, distinguishing them from commercial counterparts through material and testing specifications.

Replacement Considerations

Direct substitutes include other manufacturers' equivalents meeting the same MIL-M-38510 specification. Verify pinout compatibility before substitution. Cross-reference LS series timing parameters to ensure signal integrity is maintained in the target application.
