Overview
The JM38510/38301BRA is a military-grade octal buffer and line driver manufactured by Texas Instruments. It features three-state outputs and operates within a voltage range of 4.5 V to 5.5 V. The device utilizes bipolar technology and provides inverted output functionality. It is housed in a 20-pin ceramic dual in-line package (CDIP) designed for high reliability. The component supports an extended operating temperature range from -55 °C to 125 °C, ensuring performance in harsh environments.
Feature Summary
- Octal configuration providing eight independent buffer channels
- Three-state output capability for bus-oriented applications
- Military-grade construction with ceramic metal-sealed packaging
- Inverted output logic function
Applications
- Military aerospace systems requiring high-reliability logic drivers
- Bus-oriented memory and data transmission circuits
- Harsh environment industrial control interfaces
- High-speed signal buffering in defense electronics
Procurement Notes
Verify the specific revision level and manufacturer lot traceability when sourcing this military component. Confirm that the CDIP-20 package matches your board layout requirements. Ensure the supplier provides documentation confirming compliance with the JM38510 military specification standards. Check for any specific handling instructions related to the ceramic package integrity during installation.
Selection Notes
Select this component when an octal buffer with three-state control is required for military or high-reliability applications. The bipolar technology offers specific drive characteristics suitable for TTL loads. Consider the 20-pin CDIP footprint constraints and thermal management needs for the -55 °C to 125 °C operating range. Verify compatibility with existing system voltage levels between 4.5 V and 5.5 V.
Part Context
This part belongs to the SN54ALS series family, adapted for military specifications under the JM38510 designation. It serves as a robust alternative to commercial grade logic drivers in demanding environments. The device complements other ALS series components by providing high-speed buffering capabilities with enhanced durability and temperature tolerance for critical infrastructure.
Replacement Considerations
The SN54ALS240A is a confirmed commercial equivalent offering similar octal buffer functionality with three-state outputs. Verify pinout compatibility and electrical parameters before substitution. Note that the commercial version may lack the specific military qualification and ceramic packaging of the JM38510 variant.
