LTC1382CSW#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC1382CSW#TRPBF is a low power RS232 transceiver featuring two drivers and two receivers, housed in an 18-lead plastic SO (wide) package. It operates from a single 5V supply with a quiescent current of 220µA and drops to 0.2µA in shutdown mode. The device supports data rates up to 120kBaud using four 0.1µF capacitors for the charge pump. Driver outputs provide voltage swings of ±5.0V to ±7.0V, while receiver inputs withstand ±25V without damage. The component includes ESD protection rated at ±10kV and functions within a commercial temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with 220µA quiescent current and 0.2µA shutdown current
• Integrated charge pump requiring only four small 0.1µF capacitors
• Robust I/O lines capable of withstanding ±25V forcing voltages without damage
• High ESD protection rating of ±10kV on all RS232 pins

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 this component. Confirm the CSW designation corresponds to the wide 18-lead SOIC package variant. Ensure the order matches the commercial temperature grade requirements for the intended deployment environment.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring minimal power consumption in portable systems. The 18-lead wide SO package facilitates surface mount assembly. Verify that the 120kBaud maximum data rate meets system timing constraints. Consider the 0.1µF external capacitor requirement for charge pump functionality during schematic design.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC1382 family of ultra-low power RS232 transceivers. It shares pin compatibility with the LT1180A series. Related parts include the LTC1383, LTC1384, and LTC1385, which offer variations in package size or shutdown behavior while maintaining similar power characteristics.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states the device is pin compatible with the LT1180A. Designers should verify electrical specifications against the LT1180A datasheet to ensure functional equivalence in existing designs.
