DS26LS31CN/NOPB

Overview

The DS26LS31CN/NOPB is a quad high-speed differential line driver designed for digital data transmission over balanced lines. It meets EIA Standard RS-422 and Federal Standard 1020 requirements, providing unipolar differential drive to twisted-pair or parallel-wire transmission lines. The device operates from a single 5V supply with a voltage range of 4.75V to 5.25V. It features TRI-STATE outputs, short-circuit protection, and complementary outputs. The inputs are LS-compatible and function as one unit load. The component is housed in a 16-pin PDIP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides four independent line drivers within a single package for maximum density
• Features TRI-STATE outputs that do not load the line when VCC is 0V
• Includes output short-circuit protection and complementary outputs
• Inputs are LS-compatible logic requiring only one unit load

Applications

• Digital data transmission over balanced lines
• RS-422 communication systems
• Federal Standard 1020 compliant interfaces

Procurement Notes

Verify the specific ordering suffix against current Texas Instruments documentation to confirm lead-free status and packaging details. Confirm availability status as the component may be subject to lifecycle changes. Ensure compatibility with existing system power supplies and signal levels before procurement.

Selection Notes

Select this component for applications requiring RS-422 compliance and high-speed differential signaling. Verify that the commercial temperature range of 0°C to +70°C meets environmental requirements. Consider pin-compatible alternatives like the AM26LS31 if military-grade specifications are needed.

Part Context

This part belongs to the DS26LS31 family of quad differential line drivers manufactured by Texas Instruments. It is the commercial temperature variant packaged in a standard DIP format. The NOPB suffix indicates a lead-free and RoHS-compliant version of the original DS26LS31CN.

Replacement Considerations

The AM26LS31 is a pin-compatible alternative offering extended temperature ranges. For transceiver functionality, consider the LTC486CN#PBF. Verify interface standards and package dimensions when substituting.
