DS26LV31TN

Overview

The DS26LV31TN is a quad differential line driver manufactured by National Semiconductor, now part of Texas Instruments. It operates within a single 3V to 3.6V supply voltage range and supports data transmission rates up to 65 Mbps. The device complies with EIA-422-B interface standards and features low-voltage CMOS technology for reduced power consumption. It is housed in a 16-pin Plastic Dual In-Line Package (PDIP) with an operating temperature range extending from -40°C to +85°C. The component provides four independent drivers with standard input characteristics and differential outputs.

Feature Summary

• Supports high-speed differential signaling compliant with EIA-422-B standards
• Operates on a single low-voltage power supply for energy efficiency
• Integrates four independent line drivers in a single package

Applications

• Industrial communication networks requiring RS-422 compatibility
• Data acquisition systems utilizing differential signal transmission
• Telecommunications equipment interfaces

Procurement Notes

Verify the manufacturer designation as National Semiconductor or Texas Instruments, noting the corporate acquisition history. Confirm the PDIP-16 package type and ensure the RoHS compliance status matches project requirements, as indicated by specific suffixes or manufacturing dates. Cross-reference the datasheet version to confirm pinout and electrical specifications remain consistent with current documentation.

Selection Notes

Select this component when a quad differential driver is required for RS-422 applications. Ensure the design accommodates the 3V to 3.6V supply voltage constraint. Verify that the through-hole PDIP-16 package fits the PCB layout constraints. Compare against LVDS variants if lower voltage swing or higher speed is needed, as this device follows standard EIA-422 levels rather than low-voltage differential signaling.

Part Context

This device belongs to the DS26LV31 family of enhanced CMOS quad differential line drivers. It serves as the transmitter counterpart to receivers like the DS26LV32. The 'TN' suffix specifically denotes the PDIP-16 plastic dual in-line package variant. The product line was originally developed by National Semiconductor before being integrated into Texas Instruments' portfolio following their acquisition.

Replacement Considerations

The AM26LV31 series offers surface-mount alternatives such as the AM26LV31IDR. Verify package compatibility and pinout alignment when substituting DIP packages with SOIC variants. Check for equivalent electrical performance regarding drive strength and data rate capabilities.
