LTC1384ISW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1384ISW#TRPBF is an ultra-low power RS-232 transceiver manufactured by Analog Devices Inc. It features two drivers and two receivers operating from a single 5V supply, with a typical quiescent current of 220µA in Normal mode and 35µA in Shutdown mode while keeping receivers active. The device supports data rates up to 120kBaud and utilizes four 0.1µF capacitors for its charge pump. It provides ±10kV ESD protection on I/O lines and operates within an industrial temperature range of -40°C to +85°C. The component is housed in an 18-lead plastic SO (SW) package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with dedicated shutdown mode that maintains receiver functionality
• Integrated charge pump requiring only four small 0.1µF capacitors
• Robust input/output protection against overvoltage and electrostatic discharge

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 ISW designation corresponds to the industrial temperature grade (-40°C to +85°C) and the SW package type. Ensure compatibility with existing PCB footprints for the 18-lead wide SOIC format before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring minimal power consumption during standby while maintaining serial port monitoring capabilities. It serves as a pin-compatible alternative to the LT1180A. Consider the 120kBaud speed limit and 5V supply requirement when designing interface circuits for legacy serial communication systems.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1384 family of low-power RS-232 transceivers. It shares functional similarities with the LTC1382 and LTC1383 but differs in package configuration and thermal rating. The ISW variant specifically denotes the industrial temperature range and surface-mount plastic SOIC packaging suitable for automated assembly processes.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet identifies the LT1180A as a pin-compatible alternative. Designers should verify electrical parameter overlaps and temperature ratings when substituting other devices from the broader RS-232 transceiver category.
