LTC1386IS#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1386IS#TRPBF is a low-power EIA/TIA562 transceiver manufactured by Analog Devices Inc. It operates from a single 3.3V supply and features two drivers and two receivers. The device utilizes a charge pump requiring four 0.1µF capacitors to generate internal voltage rails. It supports data rates up to 120kBaud with a 1000pF, 3kΩ load. The quiescent supply current is 200µA at no load within the commercial temperature range (0°C to 70°C) and increases to 350µa–1mA in the industrial range (-40°C to 85°C). Driver outputs provide voltage swings of ±3.7V to ±4.5V into a 3kΩ load. Receiver inputs tolerate forced voltages up to ±25V without damage.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation designed for battery-powered portable systems
• Robust input protection allowing receiver lines to withstand ±25V forcing voltages
• ESD protection rated at ±10kV human body model on driver and receiver pins
• Minimal external component requirement using only four 0.1µF capacitors

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IS designation corresponds to the -40°C to 85°C industrial operating temperature range required for your application environment. Ensure the ordering information matches the exact manufacturer part number to avoid compatibility issues with pinouts or electrical characteristics.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring EIA/TIA562 compliance with minimal power consumption. It serves as a direct pin-compatible replacement for the LT1181A. Consider the 3.3V supply constraint and the need for external charge pump capacitors. Verify that the 120kBaud maximum data rate meets system timing requirements under the expected load conditions.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1386 family of ultra-low power RS-232/EIA/TIA562 transceivers. It is distinct from the 5V variants like the LTC1382 or LTC1383. The 'IS' grade specifies the wider industrial temperature range compared to the 'C' grade. The '#TRPBF' suffix denotes the specific reel packaging format for automated assembly.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states the device is pin compatible with the LT1181A. Designers replacing other components should verify that the target device supports the same 3.3V single-supply architecture and similar low quiescent current specifications.
