JM38510/32801BCA

Overview

The JM38510/32801BCA is a quad bus transceiver manufactured by Texas Instruments, designed for military and aerospace applications. It features inverting logic with three-state outputs to facilitate bidirectional data transfer on multiple buses. The device operates within a supply voltage range of 4.5V to 5.5V and supports a load capacitance of up to 45 pF. It utilizes a 20-lead ceramic flatpack (CFP) package and is rated for an extended operating temperature range from -55°C to 125°C.

Feature Summary

• Provides four independent bidirectional bus transceivers with inverting functionality
• Features three-state outputs to isolate the bus when not actively driving
• Constructed with hermetic ceramic packaging for harsh environment reliability

Applications

• Military avionics data bus systems
• Aerospace computing memory interfaces
• Ruggedized industrial control networks

Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the component meets the required MIL-STD-883 or equivalent qualification standards for your application. Confirm that the ceramic flatpack package dimensions match your PCB footprint exactly before procurement.

Selection Notes

Select this component when a high-reliability, radiation-tolerant bus interface is required for critical systems. It is suitable for designs needing isolated bidirectional data paths with defined drive strengths. Consider the thermal management requirements associated with the ceramic package and the specific voltage levels supported by the LS logic family.

Part Context

This part belongs to the JM38510 series, which represents military-grade versions of standard logic components. These parts are typically produced under strict quality controls to meet DoD specifications. The 32801 designation specifically identifies the quad bus transceiver function within this broader family of digital logic devices.

Replacement Considerations

Direct replacements include other qualified JM38510/32801 variants from authorized manufacturers. Verify that any substitute maintains the same 20-lead CFP package and electrical characteristics. Cross-reference with commercial equivalents only if environmental ratings can be downgraded appropriately.
