26LS32PC

Overview

The Rochester Electronics LLC 26LS32PC is a quad differential line receiver component belonging to the AM26LS32A family. It functions as an RS-422 interface integrated circuit designed for balanced and unbalanced digital data transmission applications. The device incorporates four independent receivers, each equipped with enable functionality to support bus-oriented system architectures. It operates within a standard 5 V power supply range, specifically between 4.75 V and 5.25 V, while maintaining a typical operating supply current of 70 mA. The component supports data rates up to 10 Mb/s and is housed in a PDIP-16 package suitable for through-hole mounting.

Feature Summary

• Quad differential line receiver architecture supporting RS-422 communication standards
• Integrated enable functionality on all receivers for flexible bus system integration
• Enhanced sensitivity and input impedance compared to previous generation devices

Applications

• Balanced digital data transmission systems
• RS-422 interface circuits
• Bus-oriented system interconnects

Procurement Notes

Verify the specific manufacturing lot and date code against project requirements, as Rochester Electronics sources end-of-life components from various channels. Confirm that the PDIP-16 through-hole package matches the target PCB footprint. Ensure the device meets the required environmental specifications for the intended operational temperature range before finalizing procurement decisions.

Selection Notes

Select this component when a quad differential receiver with enhanced sensitivity is required for RS-422 networks. The 26LS32PC offers improved input impedance to reduce bus loading compared to earlier variants. Verify compatibility with existing system voltage levels and ensure the through-hole packaging aligns with the assembly process constraints.

Part Context

This part is manufactured by Rochester Electronics LLC, which specializes in providing lifecycle solutions for obsolete and hard-to-find semiconductors. The 26LS32PC is a variant of the Texas Instruments AM26LS32A series, maintained through licensed manufacturing or die sourcing to support long-term industrial and commercial applications requiring legacy interface components.

Replacement Considerations

Direct functional equivalents include the AM26LS32ACN and AM26LS32AIDR. Verify pinout compatibility and electrical parameters before substitution. Note that package differences may require adapter boards or re-layout.
