LTC1382ISW#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC1382ISW#TRPBF is a low-power RS-232 transceiver manufactured by Analog Devices Inc. It operates from a single 5V supply and features two drivers and two receivers. The device draws 220µA in normal mode and 0.2µA in shutdown mode. It supports data rates up to 120kBaud with a 2500pF, 3kΩ load. ESD protection exceeds ±10kV, and I/O lines withstand ±25V without damage. It uses four 0.1µF capacitors for the charge pump. The ISW suffix indicates an industrial temperature range of -40°C to +85°C in an 18-lead SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power consumption with dedicated shutdown mode reducing current to 0.2µA
• Robust input/output protection against overvoltage and electrostatic discharge
• Minimal external component requirement using only four small capacitors
• TTL/CMOS compatible logic inputs and outputs

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers
• Battery-powered serial communication systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms the reel packaging format required for automated assembly processes. Confirm that the ISW designation matches the necessary industrial temperature operating range for the target environment. Ensure compatibility with existing bill of materials regarding the 18-lead SOIC footprint and pinout configuration before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when ultra-low quiescent current is critical for battery life in portable devices. It serves as a direct pin-compatible replacement for the LT1180A series. Consider the 120kBaud maximum speed limit when designing high-speed serial links. Verify that the single 5V supply constraint aligns with the system power architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1382 family of 5V RS-232 transceivers. It shares functional similarities with the LTC1383 but utilizes a wider 18-lead SOIC package instead of a narrow 16-lead variant. The device is designed specifically for applications requiring minimal power dissipation while maintaining standard RS-232 signal integrity.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly states the device is pin compatible with the LT1180A. Designers replacing legacy components should verify that the electrical characteristics of the substitute meet the original design specifications for voltage levels and drive strength.
