M38510/12903BPA

Overview

The M38510/12903BPA is a military-grade dual peripheral driver from the SN5545xB family, manufactured by Texas Instruments. It features an OR logic function with open-collector outputs capable of driving up to 300mA at voltages reaching 30V. The device operates within a temperature range of -55°C to 125°C and utilizes a ceramic DIP-8 package.

Feature Summary

• Dual-output drivers with integrated OR logic gates
• High-current capability up to 300mA per channel
• Open-collector outputs for high-voltage switching
• TTL-compatible diode-clamped inputs

Applications

• High-speed logic buffers
• Power drivers
• Lamp drivers
• LED drivers
• Line drivers

Procurement Notes

Verify that the component matches the specific MIL-M-38510 specification requirements. Confirm the package type is CDIP-8 and check for any suffix variations that may indicate different screening levels or lead finishes. Ensure the supplier provides traceability documentation consistent with military procurement standards.

Selection Notes

Select this part when a dual-channel driver with OR logic functionality is required for military applications. It replaces older SN75450 series devices while maintaining similar speed characteristics. Consider the thermal dissipation ratings if operating near maximum current limits in enclosed environments.

Part Context

This component belongs to the SN5545xB family of dual peripheral drivers designed for systems employing TTL logic. It is functionally interchangeable with previous SN75450 and SN75450A families but offers improved latch-up immunity. The SN5545xB variants are specifically characterized for full military temperature ranges.
