DS26LV31TM/NOPB

Overview

The DS26LV31TM/NOPB is a 3V enhanced CMOS quad differential line driver manufactured by Texas Instruments. It integrates four independent drivers compliant with RS-422 standards, designed for high-speed data transmission up to 10 Mb/s. The device operates within a supply voltage range of 3.0 V to 3.6 V and features low power consumption with a typical quiescent current of 125 µA. It utilizes a 16-pin SOIC surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent differential line drivers in a single package
• Compliant with RS-422 interface standards for reliable communication
• Optimized for low power operation with enhanced CMOS technology
• Supports data rates up to 10 Mb/s for high-speed applications

Applications

• RS-422 serial communication bus systems
• Industrial control networks requiring differential signaling
• Data acquisition systems with multiple transmitter nodes
• Telecommunications equipment utilizing 3V logic interfaces

Procurement Notes

Verify the presence of the NOPB suffix to confirm lead-free compliance and RoHS adherence. Ensure the TM suffix indicates tape-and-reel packaging suitable for automated assembly processes. Cross-reference the manufacturer date code to verify component freshness and storage history prior to integration into production lines.

Selection Notes

Select this component when designing circuits requiring four independent RS-422 transmitters powered by a 3V supply. It is appropriate for space-constrained designs needing surface-mount solutions. Consider thermal management requirements given the SOIC-16 package profile and ensure signal integrity measures are implemented for high-speed differential traces.

Part Context

This part belongs to the DS26LV31 family of enhanced CMOS line drivers. It serves as the transmitting counterpart to receivers like the DS26LV32 series. The device maintains compatibility with legacy RS-422 specifications while offering improved performance characteristics over older bipolar technologies, making it suitable for modern low-voltage digital systems.

Replacement Considerations

Direct functional substitutes include the DS26LV31T and DS26LV31TMX variants from Texas Instruments. Verify pinout compatibility and electrical parameters before substitution. Alternative packages such as TSSOP or QFN may require schematic layout adjustments despite identical internal functionality.
