M38510/32503BRA

Overview

The M38510/32503BRA is an octal buffer and line driver manufactured by Texas Instruments under the MIL-M-38510 specification. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes TTL input logic and provides high-level output current of -3 mA and low-level output current of 24 mA. It exhibits a propagation delay of 10 ns. The component is housed in a 20-pin ceramic dual in-line package (CDIP) designed for through-hole mounting. It supports an extended industrial temperature range from -55°C to +125°C, ensuring reliability in demanding environments.

Feature Summary

• Octal buffering capability with three-state outputs for efficient bus driving
• TTL-compatible input logic levels for standard digital interface integration
• Robust ceramic packaging suitable for high-reliability military applications

Applications

• Military-grade data bus systems requiring high noise immunity
