LTC1385IG#PBF

Drivers, Receivers, Transceivers Overview

The LTC1385IG#PBF is a 2-driver/2-receiver EIA/TIA-562 transceiver operating from a single 3.3V supply. It features ultra-low power consumption with quiescent current of 0.2mA in shutdown mode and 35mA in driver disable mode. The device supports data rates up to 120kBaud and utilizes four 0.1µF capacitors for its charge pump. It provides robust protection, including receiver inputs forced to –25V without damage and ESD protection exceeding –10kV. The component operates within an industrial temperature range of –40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with dedicated shutdown and driver disable modes
• Robust I/O protection allowing –25V input tolerance and high ESD immunity
• Single 3.3V supply compatibility with minimal external capacitor requirements

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure the procurement channel sources directly from authorized distributors or the manufacturer to guarantee authenticity. Cross-reference the full part number with the latest datasheet revision to confirm pinout and electrical specifications match the design requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring low power RS-562 communication in portable electronics. Verify that the system operates on a single 3.3V rail. Confirm that the required data rate does not exceed 120kBaud. Check if the industrial temperature range (–40°C to +85°C) meets environmental constraints. Consider the SSOP-20 package dimensions for PCB layout compatibility.

Drivers, Receivers, Transceivers Part Context

The LTC1385 series includes variants such as the CG, CN, CSW, IN, and ISW, differing primarily in package style and operating temperature range. The IG suffix specifically denotes the industrial temperature grade housed in a 20-lead SSOP package. This places it within the broader family of 3.3V low-power RS-562 transceivers designed for battery-operated devices.

Drivers, Receivers, Transceivers Replacement Considerations

The LT1780/LT1781 are listed as related parts but operate at 5V and offer higher ESD ratings. Direct pin-compatible replacements within the same voltage and temperature class should be verified via official substitution guides.
