JM38510/32901BCA

Overview

The JM38510/32901BCA is a military-grade 9-bit odd/even parity generator and checker from Texas Instruments. It belongs to the ALS logic family and features six independent buffer functions within a single package. The device operates in a temperature range of -55°C to 125°C and utilizes a 14-pin ceramic dual in-line package (CDIP). It supports complementary outputs for robust signal integrity in high-reliability applications.

Feature Summary

• Provides dedicated hardware support for generating and checking 9-bit parity data streams
• Features six independent buffer channels for signal isolation and driving
• Constructed with metal-sealed ceramic packaging for harsh environment resilience

Applications

• Military communication systems requiring error detection
• Avionics data bus interfaces
• High-reliability industrial control networks

Procurement Notes

Verify the specific suffix designation, such as BCA or BCA.A, against the purchase order to ensure correct manufacturing lot and compliance with MIL-STD specifications. Confirm that the component meets the required environmental qualification standards for the intended deployment zone before finalizing acquisition.

Selection Notes

Select this component when a 9-bit parity solution is required alongside multiple buffered outputs in a space-constrained military form factor. Ensure the system design accommodates the CDIP-14 footprint and thermal characteristics associated with ceramic packages operating at extended temperature ranges.

Part Context

This part is part of the SN54LS280 family, adapted for military reliability standards under the JM38510 specification. It serves as a radiation-hardened and vibration-resistant alternative to commercial logic equivalents, ensuring consistent performance in defense and aerospace environments where standard TTL components may fail.

Replacement Considerations

Direct replacements include other JM38510/32901 variants with compatible suffixes. Verify pinout compatibility and electrical parameters against SN54LS280 datasheets if substituting with non-military grade parts, though environmental ratings will differ.
