JM38510/12908BPA

Overview

The JM38510/12908BPA 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 switching. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an off-state output voltage up to 35 V. It provides continuous collector currents up to 400 mA and peak currents up to 500 mA. Characterized for operation from -55 °C to 125 °C, it utilizes a ceramic dual in-line package (CDIP) with 8 pins.

Feature Summary

• High-voltage output capability with no latch-up at 30 V after conducting rated current
• TTL-compatible diode-clamped inputs ensuring reliable interface with standard logic families
• Dual configuration providing independent NAND logic functions with integrated power drivers
• Robust construction designed for harsh environments with extended temperature range support

Applications

• Logic buffers requiring high breakdown voltages
• Power drivers for industrial control systems
• Relay drivers in aerospace applications
• Lamp drivers for specialized lighting circuits
• MOS drivers for gate control applications

Procurement Notes

Verify that the component matches the specific military qualification standards required for your system. Confirm the package type is the Ceramic Dual In-Line Package (CDIP) as indicated by the JG suffix. Ensure the operating environment falls within the specified -55 °C to 125 °C range. Check for any specific lot traceability requirements mandated by defense contracts. Validate input logic levels against TTL compatibility specifications before integration.

Selection Notes

Select this component when higher breakdown voltages are needed compared to standard peripheral drivers like the SN55451 series. Consider the trade-off between increased voltage tolerance and slightly slower switching speeds. Evaluate power dissipation ratings based on the specific package thermal characteristics. Ensure the application does not exceed the continuous or peak current limits defined in the absolute maximum ratings. Verify that the NAND logic function aligns with the circuit design requirements.

Part Context

This part belongs to the Series 55461/75462 family of dual peripheral drivers. It is designed for systems requiring higher breakdown voltages than standard devices can provide. The device is functionally interchangeable with other members of the 5546x series but offers enhanced voltage handling capabilities. It represents a specialized solution for high-reliability digital-to-power interface applications.

Replacement Considerations

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