SN75179BDR

Drivers, Receivers, Transceivers Overview

The SN75179BDR is a Texas Instruments RS-422/RS-485 interface IC featuring a differential driver and receiver pair in an SOIC-8 package. It supports data rates up to 10 Mb/s with full duplex communication. The device operates on a single 5 V power supply, ranging from 4.75 V to 5.25 V, with a typical operating current of 70 mA. It functions within a temperature range of 0°C to +70°C and includes shutdown capability for power management.

Drivers, Receivers, Transceivers Feature Summary

• Integrates one differential driver and one differential receiver for bidirectional data communication.
• Supports full duplex transmission allowing simultaneous data flow in both directions.
• Includes shutdown functionality to minimize power consumption when the bus is idle.

Drivers, Receivers, Transceivers Applications

• Multipoint communication systems requiring balanced transmission lines.
• Industrial control networks utilizing RS-422 or RS-485 standards.
• Noisy environments where high common-mode voltage rejection is required.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage requirements and thermal constraints before integration. Cross-reference datasheet revisions to validate pinout consistency and electrical characteristics for the specific batch.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full duplex operation over long bus lines. Compare against half-duplex alternatives like the SN75176B if bidirectional single-direction communication suffices. Evaluate power consumption limits and ensure the 5 V supply rail aligns with the system architecture. Consider thermal performance within the specified industrial temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75179B series of line transceivers designed for EIA-422-B and EIA-485-A standards. It provides robust signal integrity for multipoint networks. The SOIC-8 surface mount package facilitates automated assembly and compact circuit board design compared to through-hole options.

Drivers, Receivers, Transceivers Replacement Considerations

SN75179BPSR offers identical electrical specifications in a plastic small outline package variant. Verify pin-to-pin compatibility and thermal dissipation characteristics when substituting between DR and PSR suffixes.
