LTC1382CSW#PBF

Drivers, Receivers, Transceivers Overview

The LTC1382CSW#PBF 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 quiescent supply current is 220µA, dropping to 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. The device uses four 0.1µF capacitors for the charge pump and is housed in an 18-lead SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with dedicated shutdown mode reducing supply current to 0.2µA
• Robust input/output protection allowing ±25V forcing without damage and ±10kV ESD tolerance
• Minimal external component requirement utilizing only four 0.1µF capacitors for charge pumping
• TTL/CMOS compatible logic inputs and outputs with integrated pull-up resistors

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the SW package designation matches the required 18-lead plastic small outline footprint for PCB layout. Ensure the C grade temperature range (0°C to 70°C) aligns with the operational environment requirements before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring minimal power consumption in portable devices. The 18-lead SOIC package offers a compact solution compared to wider packages. Consider the 0°C to 70°C commercial temperature range; if industrial temperatures are needed, verify availability of the ISW variant. The pinout is compatible with the LT1180A for potential design swaps.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC1382 family of ultra-low power RS-232 transceivers. It is designed specifically for battery-powered systems where power conservation is critical. The device integrates a charge pump to generate the necessary positive and negative voltages from a single 5V supply, eliminating the need for external dual supplies.
