DS26LS32CM/NOPB

Overview

The DS26LS32CM/NOPB is a quad differential line receiver manufactured by Texas Instruments, designed for balanced and unbalanced digital data transmission. It complies with RS-422, RS-423, Federal Standards 1020, and 1030 specifications. The device operates from a single 5V supply (4.75V to 5.25V) and features TRI-STATE outputs with 8mA sink capability. It provides high common-mode input voltage ranges of ±7V and an input sensitivity of 200mV over this range. The component includes 100mV input hysteresis and a minimum input impedance of 6kΩ. It is housed in a 16-pin SOIC package and supports commercial operating temperatures from 0°C to +70°C.

Feature Summary

• Supports RS-422, RS-423, and Federal Standards 1020/1030 for reliable data transmission
• Features TRI-STATE outputs with 8mA sink capability for direct bus interfacing
• Includes 100mV input hysteresis to prevent output oscillation on noisy lines
• Provides high common-mode rejection with ±7V input voltage tolerance

Applications

• Balanced digital data transmission systems
• Unbalanced digital data transmission systems
• RS-422 interface circuits
• RS-423 interface circuits

Procurement Notes

Verify the specific suffix 'NOPB' against current TI documentation to confirm lead-free status and RoHS compliance details. Confirm the 'CM' designation matches the required commercial temperature range (0°C to +70°C). Check for any obsolescence notices or lifetime buy announcements associated with this specific part number before finalizing procurement plans.

Selection Notes

Select the DS26LS32CM/NOPB when designing for commercial environments requiring RS-422 or RS-423 compatibility. Ensure the application utilizes a single 5V power supply within the 4.75V to 5.25V range. Verify that the system requires four independent differential receivers with TRI-STATE control. Consider the ±7V common-mode range if the transmission lines experience significant ground potential differences.

Part Context

This component belongs to the DS26LS32 family of quad differential line receivers produced by Texas Instruments. It shares functional similarities with the DS26LS32AC and DS26LS32M variants but differs in manufacturing process and temperature rating. The 'CM' suffix indicates the commercial grade version, while 'NOPB' denotes non-plated lead-free packaging compliant with environmental standards.

Replacement Considerations

DS26LS32ACM/NOPB: Similar quad receiver with enhanced input sensitivity and pull-up/pull-down resistors. DS26LS32CMX/NOPB: Same device in tape-and-reel packaging instead of tube.
