M38510/12908BPA

Overview

M38510/12908BPA is a military-grade dual peripheral driver manufactured by Texas Instruments, functionally equivalent to the SN55462. It features two NAND logic gates with outputs connected to NPN transistors for high-voltage and high-current driving. The device operates over a temperature range of -55°C to 125°C and supports supply voltages up to 7V. It provides continuous output currents up to 400mA and peak currents up to 500mA, with an off-state breakdown voltage of 35V. The component utilizes a ceramic dual in-line package (CDIP) with 8 pins.

Feature Summary

• High-voltage output capability with no latch-up at 30V after conducting rated current
• TTL-compatible diode-clamped inputs for direct interface with standard logic families
• Dual configuration providing independent NAND logic functions per channel
• Robust construction designed for harsh environments with extended thermal stability

Applications

• Logic buffers requiring high breakdown voltage tolerance
• Power drivers for industrial control systems
• Relay drivers in aerospace and defense applications
• Lamp drivers for specialized lighting circuits
• Line drivers for long-distance signal transmission

Procurement Notes

Verify that the specific M38510/12908BPA designation corresponds to the QML certified military version rather than commercial variants. Confirm package integrity for the CDIP-8 form factor upon receipt. Ensure handling procedures account for the ceramic material properties and lead frame specifications defined in the datasheet to maintain reliability standards.

Selection Notes

Select this component when system requirements demand higher breakdown voltages than standard peripheral drivers can provide, accepting slightly slower switching speeds as a trade-off. It serves as a drop-in replacement for SN55451B through SN55453B series devices where enhanced voltage tolerance is critical. Consider the medium-speed switching characteristics against application timing constraints.

Part Context

This part belongs to the Series 55461/75461 family of dual peripheral drivers. It is specifically the NAND logic variant within this family, distinct from the AND (SN55461) and OR (SN55463) configurations. The M38510 prefix indicates it is a military specification microcircuit, ensuring compliance with rigorous quality and performance standards for defense and aerospace use cases.

Replacement Considerations

Functionally interchangeable with SN55451B through SN55453B and SN75451B through SN75453B peripheral drivers.
