M38510/31202BEA

Specialty Logic Overview

The M38510/31202BEA is a military-grade, 4-bit full adder/subtractor belonging to the LS (Low-Power Schottky) logic series. Manufactured by Texas Instruments, it features internal carry lookahead and supports ripple carry cascading for multi-bit arithmetic operations. The component is housed in a 16-pin ceramic dual in-line package (CDIP). It operates within an extended temperature range of -55°C to 125°C and complies with MIL-M-38510 specifications.

Specialty Logic Feature Summary

• Internal carry lookahead mechanism for high-speed arithmetic processing
• Supports ripple carry cascading for scalable multi-bit configurations
• Dual functionality as both a 4-bit adder and subtractor

Specialty Logic Applications

• Military defense systems requiring radiation-hardened or high-reliability digital logic
• Space-based avionics and satellite telemetry control units
• High-performance computing arithmetic logic units (ALUs)

Specialty Logic Procurement Notes

Verify that the specific ordering suffix matches the required package style, as the base part number corresponds to multiple physical form factors. Confirm compliance with MIL-M-38510 Class B standards and ensure the lead finish meets environmental requirements for your assembly process. Cross-reference the datasheet revision date against your design timeline to validate technical accuracy.

Specialty Logic Selection Notes

Select this component when designing systems that demand Low-Power Schottky performance characteristics combined with military-grade reliability. Ensure the application environment remains within the specified -55°C to 125°C operational limits. Verify that the 16-pin CDIP footprint aligns with the target printed circuit board layout constraints.
