LTC1483IS8#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1483IS8#TRPBF is an ultra-low power RS-485/RS-422 differential line transceiver in an 8-lead SOIC package. It operates on a single 5V supply (4.75V to 5.25V) with a maximum data rate of 250kbps. Quiescent current is typically 80µA when disabled and 500µA when enabled without load, dropping to 1µA in shutdown mode. The device features a controlled slew rate driver for reduced EMI, a –7V to +12V common-mode range, and thermal shutdown protection. Receiver input hysteresis is 45mV, and I/O pins provide ±10kV ESD protection.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power CMOS design with shutdown capability
• Controlled slew rate driver for low electromagnetic interference
• Extended common-mode voltage range beyond supply rails
• Fail-safe receiver with high output state during open inputs

Drivers, Receivers, Transceivers Applications

• Battery-powered RS-485/RS-422 communication systems
• Industrial bus networks requiring low power consumption
• Level translation applications
• Systems sensitive to electromagnetic radiation

Drivers, Receivers, Transceivers Procurement Notes

Verify the #TRPBF suffix indicates tape and reel packaging suitable for automated assembly. Confirm the IS8 designation corresponds to the industrial temperature range (-40°C to +85°C) and the SOIC-8 package style. Ensure compliance with RoHS directives as indicated by the PBF suffix before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs prioritizing minimal quiescent current draw over high-speed transmission. The 250kbps limit suits slower industrial protocols. Verify that the system requires a single 5V supply and benefits from the extended common-mode range. Consider the thermal shutdown feature for fault tolerance in harsh environments.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1483 series of ultra-low power transceivers. It is pin-compatible with the LTC485 but offers lower power consumption due to its CMOS architecture. The IS8 variant specifically denotes the industrial temperature grade and surface-mount plastic SOIC package format.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC485 is a pin-compatible alternative. For 3.3V operation, consider the LTC1480. Higher speed requirements may necessitate the LTC1485 or LTC1487.
