LTC1385CSW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1385CSW#TRPBF is a 2-driver/2-receiver EIA/TIA-562 transceiver operating from a single 3.3V supply. It features low supply current of 200mA in normal mode, dropping to 35mA in Driver Disable and 0.2mA in Shutdown. The device uses four 0.1µF capacitors for its charge pump and supports data rates up to 120kBaud. Receiver inputs withstand –25V without damage, and the unit provides –10kV ESD protection. It operates within a commercial temperature range of 0°C to 70°C and is housed in an 18-lead SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with dedicated shutdown and driver disable modes
• EIA/TIA-562 compliance with high noise immunity via receiver hysteresis
• Robust input protection allowing forced –25V on receiver lines
• Space-saving design utilizing small 0.1µF external capacitors

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets all necessary environmental standards for the intended deployment environment before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring RS-562 communication with minimal power consumption. Ensure the system design accommodates the 3.3V supply requirement and includes the specified 0.1µF capacitors for proper charge pump functionality.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1385 family of ultra-low power RS-562 transceivers. It serves as a pin-compatible alternative to the LT1180A while offering optimized performance for 3.3V systems. The SW suffix indicates the 18-lead plastic small outline wide package configuration.

Drivers, Receivers, Transceivers Replacement Considerations

The LT1780/LT1781 offers similar functionality with higher ESD ratings per IEC 1000-4. The LTC1386 provides a comparable 3.3V solution in a narrower 16-pin SO package.
