DS75107MX

Overview

The DS75107MX is a dual differential line driver manufactured by National Semiconductor, now part of Texas Instruments. It features two independent drivers capable of transmitting data over balanced transmission lines. The device operates with a supply voltage range typically spanning 4.75 V to 5.25 V for standard logic families. It supports high-speed data transmission rates suitable for RS-422 and RS-485 communication standards. The component is housed in an 8-pin SOIC surface-mount package, designed for compact circuit board layouts.

Feature Summary

• Provides dual independent differential line driving capabilities
• Supports standard RS-422 and RS-485 communication protocols
• Utilizes tri-state outputs for bus sharing applications
• Designed for reliable operation in industrial communication environments

Applications

• RS-422 balanced digital interface circuits
• RS-485 multi-point communication networks
• Industrial process control data transmission
• Modem and telecommunications equipment interfaces

Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific suffix MX corresponds to the SOIC-8 package variant. Confirm that the device meets the required electrical specifications for your target RS-422 or RS-485 application before integration into the design.

Selection Notes

Select this component when a dual-channel differential driver is required for half-duplex or full-duplex serial communication. Compare against SN55110A equivalents for pin compatibility. Consider power consumption and propagation delay requirements relative to the system clock speed. Verify thermal performance within the chosen SOIC-8 enclosure constraints.

Part Context

This component belongs to the family of dual line drivers originally developed by National Semiconductor. These devices are foundational for establishing robust serial communication links in noisy environments. The transition to Texas Instruments has maintained the functional integrity of these legacy parts while updating manufacturing processes.

Replacement Considerations

The SN55110A is a documented equivalent from Texas Instruments offering similar dual line driver functionality. Verify pinout compatibility and electrical characteristics before substitution. Other variants in the SN551xx series may provide alternative packaging options.
