DS75150MX

Overview

The DS75150MX is a dual line driver manufactured by National Semiconductor, now part of Texas Instruments. It features a wide operating supply voltage range from 3.0 V to 5.5 V and supports data transmission rates up to 25 Mbps. The device incorporates Schmitt trigger inputs for noise filtering and provides differential outputs compatible with RS-485 and RS-422 standards. It is housed in an 8-pin SOIC package.

Feature Summary

• Dual differential line drivers supporting RS-485 and RS-422 communication protocols
• Schmitt trigger inputs designed to filter high-frequency noise and signal transients
• Wide single-supply voltage operation ranging from 3.0 V to 5.5 V
• High-speed data transmission capability with a maximum rate of 25 Mbps

Applications

• RS-485 multi-drop communication bus systems
• RS-422 point-to-point or multi-point serial data links
• Industrial control network interfaces
• Telecommunications equipment signal conditioning

Procurement Notes

Verify the manufacturer marking on the component body, as National Semiconductor was acquired by Texas Instruments. Ensure the suffix 'MX' corresponds to the specific 8-lead SOIC package variant. Confirm RoHS compliance status through official datasheets, as legacy stock may differ from current production runs.

Selection Notes

Select this component when designing circuits requiring robust differential signaling over noisy environments. The integrated Schmitt triggers make it suitable for long cable runs where signal integrity is critical. Ensure the system power supply remains within the 3.0 V to 5.5 V range to maintain specified timing parameters and output voltage levels.

Part Context

This device belongs to the DS7515x family of line drivers, which are widely used in industrial and commercial applications requiring reliable serial communication. The MX suffix denotes the plastic small-outline package (SOIC) configuration, distinguishing it from other packaging options like DIP or TSSOP available within the same functional family.

Replacement Considerations

Direct substitutes include the DS75150N (DIP package) and DS75150M (SOIC package). Cross-manufacturer equivalents such as the SN75150 from Texas Instruments or MC145562 from ON Semiconductor may be considered if pin compatibility and electrical specifications match the design requirements.
