26LS32BSC

Overview

The Rochester Electronics LLC 26LS32BSC 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. Key electrical parameters include a typical propagation delay of 6ns and a typical output skew of 0.5ns. It operates from a single 5V supply and features 3-state outputs suitable for connection to system buses.

Feature Summary

• Quad differential line driver architecture supporting RS-422 standards
• TTL and CMOS input compatibility with translation to RS-422 output levels
• 3-state outputs enabling safe connection to system buses
• Low quiescent current consumption for energy efficiency

Applications

• Digital data transmission over balanced lines
• System bus interconnections requiring 3-state isolation
• RS-422 compliant communication interfaces

Procurement Notes

Verify the specific manufacturer origin and date code upon request, as Rochester Electronics sources components through licensed manufacturing and distribution channels. Confirm that the package type matches the required board layout specifications. Ensure the component status aligns with long-term availability needs for the target application.

Selection Notes

Select this component when an RS-422 compliant quad driver with 3-state capability is required. It is suitable for designs needing TTL/CMOS input compatibility and low power operation on a 5V supply. Consider the package constraints and thermal requirements during the design phase to ensure proper integration into the final system.

Part Context

This part belongs to the family of RS-422 interface integrated circuits. It serves as a robust solution for differential signaling applications where noise immunity and reliable data transmission over balanced pairs are critical. The device complements other interface components by providing the necessary line driving capabilities for standardized serial communication protocols.

Replacement Considerations

Check for functional equivalents from other manufacturers that meet RS-422 specifications. Verify pinout compatibility and electrical parameter alignment before substitution. Ensure that any alternative component supports the same voltage levels and output drive requirements.
