DS26LV32ATMX/NOPB

Overview

The DS26LV32ATMX/NOPB is a 3V enhanced CMOS quad differential line receiver manufactured by Texas Instruments. It complies with TIA/EIA-422-B and ITU-T V.11 standards, featuring four independent receivers in a 16-pin SOIC-Narrow package. The device operates on a supply voltage ranging from 3 V to 3.6 V with a typical operating current of 15 mA. It supports a switching frequency exceeding 32 MHz and offers a common-mode range of +7 V at VP = 3 V or +10 V at VIP = 0.2 V. The component functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides universal enable control for all four receivers via active-high EN or active-low EN* pins.
• Ensures receiver outputs go high when inputs are open, offering fault-safe behavior for disconnected lines.
• Maintains compatibility with existing 5V RS-422 interop networks while operating at 3V.
• Delivers low static power consumption suitable for battery-powered applications.

Applications

• Battery-powered communication systems requiring low power dissipation
• Industrial networks adhering to TIA/EIA-422-B standards
• Telecommunications equipment utilizing ITU-T V.11 protocols

Procurement Notes

Verify the specific suffix configuration against the original design requirements before procurement. Confirm that the manufacturer's end-of-life status does not conflict with long-term production schedules. Ensure the SOIC-16 package dimensions match the PCB footprint constraints. Validate RoHS compliance documentation if required by regional regulations. Check for available alternative sources given the discontinued status.

Selection Notes

Select this component when a quad differential receiver compliant with RS-422 is needed for 3V logic interfaces. Consider the 15 mA supply current for power budget calculations. Verify that the 32 MHz switching frequency meets the data rate requirements of the application. Ensure the -40°C to +85°C operating range covers the environmental conditions. Compare pinout compatibility with legacy DS26C32AT designs if migrating existing hardware.

Part Context

This part belongs to the DS26LV32AT series of enhanced CMOS differential receivers. It serves as a successor to older bipolar technologies, offering lower power consumption and higher speed capabilities. The device integrates four receivers into a single compact package, reducing board space compared to discrete solutions. It is designed for robust signal integrity in noisy industrial environments.

Replacement Considerations

The DS26LV32ATM is a non-RoHS equivalent variant within the same family. Verify pinout compatibility before substitution. No other direct public substitutes are confirmed in the provided documentation.
