DS26LV31TM

Overview

The DS26LV31TM is a quad differential line driver manufactured by Texas Instruments, conforming to TIA/EIA-422-B and ITU-T V.11 standards. It operates on a single 3.0V to 3.6V supply with a maximum static current of 100 μA at -40°C to +85°C. The device features tri-state outputs controlled by common EN and EN* inputs. Key electrical parameters include a typical propagation delay of 10.5 ns (max 16 ns) and a maximum operating frequency of 32 MHz. Differential output voltage guarantees a minimum of 2V across the operating range. ESD protection exceeds 7 kV on cable I/O pins.

Feature Summary

• Conforms to TIA/EIA-422-B and ITU-T V.11 recommendations for industrial and military applications
• Provides balanced output crossover characteristics to minimize electromagnetic interference
• Features enhanced electrostatic discharge protection exceeding 7 kV tolerance on cable I/O pins
• Offers low power consumption suitable for battery-powered systems

Applications

• Industrial communication networks requiring RS-422 compliance
• Military aerospace systems meeting Standard Microcircuit Drawing requirements
• Low power data transmission interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and environmental rating. Confirm RoHS compliance status as indicated in the packaging information addendum. Ensure that the selected variant matches the required temperature range and lead finish specifications for the intended application environment.

Selection Notes

Select this component when a quad differential driver compliant with RS-422 standards is required for industrial or military environments. Consider the pin-compatible alternative DS26C31 if 5V operation is needed instead of the 3.3V supply range specified here. Verify that the SOIC-16 package dimensions fit the target PCB layout constraints.

Part Context

This device belongs to the DS26LV31 family of high-speed CMOS differential line drivers. It serves as a low-voltage replacement for older 5V RS-422 drivers while maintaining interoperability with existing 5V networks. The product is designed using CMOS technology to achieve low static power dissipation without compromising signal integrity at high switching rates.

Replacement Considerations

The datasheet explicitly identifies the DS26C31 as a pin-compatible alternative.
