LTC1384IG#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1384IG#TRPBF is an ultra-low power RS-232 transceiver manufactured by Analog Devices Inc., featuring two drivers and two receivers. It operates from a single 5V supply with a quiescent current of 220µA in Normal mode and drops to 35µA in Shutdown mode while keeping both 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 withstands ±25V overvoltage without damage. The component is housed in an 18-lead SOIC package and is rated for an industrial operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power consumption with dedicated shutdown mode that maintains receiver functionality
• Robust input/output protection against electrostatic discharge and high voltage overloads
• Compact design requiring only four small space-saving capacitors for charge pump operation

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms the tape and reel packaging format required for automated assembly processes. Confirm the 'I' grade designation matches the necessary industrial temperature range specifications for the target environment. Ensure the 18-lead SW package footprint aligns with the printed circuit board layout constraints.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing battery-powered portable systems requiring RS-232 connectivity with minimal standby current draw. The device is suitable for applications needing continuous monitoring via active receivers during system sleep states. Consider the 18-lead SOIC package dimensions if space constraints are critical compared to the 20-lead SSOP alternative.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1384 family of low-power RS-232 transceivers designed for single-supply operation. It serves as a pin-compatible alternative to the LT1180A, offering improved power efficiency. The series includes variants with different package options and temperature grades to support diverse embedded communication interface requirements.

Drivers, Receivers, Transceivers Replacement Considerations

The LT1780/LT1781 offers similar functionality with higher ESD ratings per IEC standards. The LTC1382 and LTC1383 provide comparable electrical characteristics with different package footprints.
