Overview
The Rochester Electronics 26LS32B/B2A is a quad differential line driver designed for digital data transmission over balanced lines. It meets the requirements of the EIA standard RS-422 while maintaining low power characteristics typical of CMOS technology. The device accepts TTL or CMOS input levels and translates them to RS-422 output levels. It features three-state outputs suitable for connection to system buses, allowing multiple drivers to share a common line. The component operates from a single 5V supply and includes protection against electrostatic discharge on all outputs.
Feature Summary
- Quad differential line driver architecture supporting RS-422 standards
- Three-state outputs enabling bus-organized system interfacing
- TTL and CMOS input level compatibility with translation to RS-422 outputs
- Electrostatic discharge protection integrated into output circuitry
Applications
- Digital data transmission over balanced lines
- System bus connections requiring multi-driver capability
- RS-422 compliant communication interfaces
Procurement Notes
Verify the specific suffix /B2A against official documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required temperature range and quality certification for your application. Cross-reference the datasheet parameters to confirm electrical characteristics align with system requirements before procurement.
Selection Notes
Select this component when a quad differential driver meeting RS-422 standards is required for balanced line transmission. Consider its three-state output capability if bus multiplexing is necessary. Verify that the single 5V supply voltage and TTL/CMOS input compatibility fit the existing logic levels of the design.
Part Context
Rochester Electronics provides manufactured components using die or wafers from original suppliers or recreated IP with approval. These parts are tested to meet or exceed original manufacturer specifications. The 26LS32B/B2A falls under their portfolio of interface and logic devices, offering lifecycle support for discontinued or hard-to-find semiconductors.
Replacement Considerations
Direct replacements include the SN75LBC184 or similar quad differential line drivers from other manufacturers that meet RS-422 standards. Verify pinout compatibility and electrical parameters such as propagation delay and output current when substituting.
