SN75ALS180NE4

Drivers, Receivers, Transceivers Overview

The SN75ALS180NE4 is a Texas Instruments RS-422/RS-485 interface IC featuring one differential driver and one receiver pair. It operates from a single 5-V supply (4.75 V to 5.25 V) with a maximum operating temperature of 70 °C. The device supports data rates up to 25 Mb/s, utilizing high-speed advanced low-power Schottky circuitry. Key electrical parameters include a maximum supply current of 30 mA, a driver output capacity of ±60 mA, and a receiver input impedance of at least 12 kΩ. It meets TIA/EIA-422-B and TIA/EIA-485-A standards.

Drivers, Receivers, Transceivers Feature Summary

• Complies with TIA/EIA-422-B, TIA/EIA-485-A, and ITU Recommendation V.11 standards for balanced transmission lines.
• Features individual driver and receiver I/O pins with dual VCC and dual GND connections for enhanced flexibility.
• Includes thermal shutdown protection and driver positive- and negative-current limiting capabilities.
• Provides glitch-free power-up and power-down protection to ensure stable operation during voltage transitions.

Drivers, Receivers, Transceivers Applications

• Bidirectional data communication on multipoint bus-transmission lines.
• Serial and parallel applications requiring high-speed data transfer.
• Party-line applications utilizing wide common-mode voltage ranges.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'E4' against the manufacturer's official documentation to confirm compliance with environmental regulations such as RoHS. Ensure the package type matches the required PCB footprint, as the standard N designation indicates a PDIP package. Cross-reference the datasheet revision history to confirm that no recent design changes affect pin compatibility or electrical characteristics before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a full-duplex transceiver is required for RS-422 or RS-485 networks within a 0 °C to 70 °C temperature range. The SN75ALS180NE4 is suitable for designs needing separate enable controls for the driver and receiver. Consider the 25 Mb/s data rate capability and low skew specifications for high-speed signal integrity requirements in industrial or commercial environments.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx5ALS180 family of differential driver and receiver pairs manufactured by Texas Instruments. The 'SN75' prefix denotes the commercial temperature grade variant, while the 'ALS' series indicates the use of advanced low-power Schottky technology. This family provides integrated solutions for bidirectional data communication on multipoint bus lines.

Drivers, Receivers, Transceivers Replacement Considerations

The SN65ALS180N serves as the industrial temperature grade equivalent. Verify if the extended -40 °C to 85 °C operating range of the SN65 variant is necessary for the application environment. Both parts share identical pinouts and electrical functions, differing primarily in their specified temperature limits.
