26LS32/B2A

Overview

The Rochester Electronics LLC 26LS32/B2A is a quad differential line receiver designed for high-speed digital data transmission over balanced lines. It complies with EIA RS-422 and FED STD 1020 standards, ensuring reliable communication in industrial environments. The device features four independent receivers with standard input characteristics and differential outputs. It operates within a specified temperature range and utilizes a ceramic dual flatpack (CDFP) package with 16 pins. This component is manufactured by Rochester Electronics, providing access to legacy interface solutions.

Feature Summary

• Supports EIA RS-422 and FED STD 1020 serial interface standards
• Provides four independent differential line receivers
• Utilizes bipolar technology for signal processing
• Features ceramic packaging for durability

Applications

• Industrial automation control systems
• Military and aerospace communication interfaces
• Harsh environment data transmission networks

Procurement Notes

Verify the specific suffix B2A against official datasheets to confirm pinout and electrical tolerances. Ensure compatibility with existing system voltage levels and thermal requirements. Confirm lead-free status if required by project specifications. Validate that the ceramic package matches the PCB footprint constraints. Check for radiation hardening requirements if used in space applications.

Selection Notes

Select this component when RS-422 compliance is mandatory for noise immunity in long-distance serial communication. Consider the ceramic package for superior thermal stability compared to plastic alternatives. Evaluate the need for four channels versus single or dual receiver options. Verify that the operating temperature range meets the environmental conditions of the deployment site.

Part Context

Rochester Electronics specializes in sourcing and manufacturing legacy semiconductors. The 26LS32 series belongs to the LS26 family of high-speed differential receivers. These components are critical for maintaining functionality in systems where original equipment manufacturer production has ceased. Rochester ensures supply continuity through wafer sourcing and assembly services.

Replacement Considerations

Direct substitutes include the Intersil HS-26CT32RH for radiation-hardened applications. Standard commercial equivalents may exist but require verification of package dimensions and electrical parameters. Ensure any replacement maintains the 16-pin CDFP form factor.
