LTC489ISW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC489ISW#TRPBF is a low-power quad RS-485 line receiver manufactured by Analog Devices Inc. It operates on a single 5V supply (4.75V to 5.25V) and features four differential receivers with three-state outputs in a 16-lead wide SOIC package. The device supports data rates up to 10Mb/s with a typical propagation delay of 28ns. It provides an extended common-mode range from -7V to +12V, allowing for significant ground differences between devices. Key electrical parameters include a typical supply current of 7mA, 60mV input hysteresis, and fail-safe functionality that guarantees a high output state when inputs are open.

Drivers, Receivers, Transceivers Feature Summary

• Fail-safe design ensures a logic high output state when differential inputs are left floating or disconnected.
• Three-state outputs maintain high impedance regardless of the power supply status or enable pin configuration.
• Extended common-mode voltage range accommodates bus environments with substantial ground potential differences.
• CMOS architecture delivers reduced power consumption compared to bipolar alternatives while maintaining robust overload protection.

Drivers, Receivers, Transceivers Applications

• Multipoint data transmission networks utilizing the RS-485 standard
• RS-422 compliant communication systems requiring differential signaling
• Level translation interfaces between different voltage domains

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging upon order confirmation. Confirm the ISW designation corresponds to the industrial temperature range and wide SOIC package format required for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad receiver topology is required without integrated driver capabilities. Ensure the system design accounts for the 7mA supply current per device and utilizes appropriate cable termination resistors to prevent signal reflections on the transmission line.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC488/LTC489 family of low-power RS-485/RS-422 receivers. It serves as the receiver-only counterpart to transceiver models like the LTC485, offering pin compatibility with legacy SN75173 and SN75175 components for straightforward circuit upgrades.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the SN75175. Other Analog Devices options such as the LTC1483 or LTC1485 provide similar interface functions but may differ in package type, speed, or power characteristics.
