Overview
The 26LS30/BFA is a dual differential line driver manufactured by Rochester Electronics, LLC. It operates on a single 5V supply and features TTL-compatible inputs with differential outputs designed for RS-422 communication standards. The device utilizes BICMOS technology to ensure high-speed data transmission over balanced lines. It is housed in a ceramic DIP package with 16 pins. The component supports an operating temperature range from -55°C to +125°C, making it suitable for military and harsh environment applications.
Feature Summary
- Dual differential line driver architecture supporting RS-422 standards
- TTL-compatible input logic levels for direct interface with digital systems
- Radiation-hardened construction ensuring reliability in severe environments
- High-speed operation capability for efficient data transmission
Applications
- Military aerospace communication systems requiring radiation tolerance
- Industrial control networks utilizing RS-422 serial interfaces
- Harsh environment data transmission links
- Spacecraft onboard data bus architectures
Procurement Notes
Verify the specific suffix 'BFA' against official datasheets to confirm package type and material composition. Confirm radiation hardness level requirements match application needs. Check for RoHS compliance status as older military parts may differ. Ensure supplier provides traceability documentation for critical deployments.
Selection Notes
Select this component when dual differential driving is required for RS-422 networks. Consider the wide temperature range for extreme environmental conditions. Verify pin compatibility with existing PCB layouts due to the specific DIP footprint. Evaluate power consumption constraints relative to system thermal design.
Part Context
Rochester Electronics specializes in sustaining legacy and obsolete semiconductor products. This part belongs to their interface and driver portfolio, often sourced from original manufacturers like AMD. It serves markets requiring long-term availability of proven technologies rather than cutting-edge innovations.
Replacement Considerations
Direct substitutes include other radiation-hardened dual differential drivers such as the AM26LS30 variants. Verify electrical parameters and pinout compatibility before substitution. Ensure replacement parts meet the same MIL-PRF or SMD specifications for critical applications.
