LTC1386CS#PBF

Drivers, Receivers, Transceivers Overview

The LTC1386CS#PBF is a low-power EIA/TIA562 transceiver manufactured by Analog Devices Inc. It operates from a single 3.3V supply and features two drivers and two receivers. The quiescent supply current is typically 200µA with unloaded outputs. The device supports data rates up to 120kBaud with a 1000pF, 3kΩ load. Driver outputs can be forced to ±25V without damage, and the inputs provide overvoltage protection against ±10kV ESD strikes. It utilizes four 0.1µF capacitors for its charge pump and is housed in a 16-lead SOIC narrow package.

Drivers, Receivers, Transceivers Feature Summary

• Ultra-low power operation with a typical 200µA supply current at 3.3V
• Robust I/O lines capable of withstanding ±25V forcing voltages without damage
• High electrostatic discharge (ESD) protection rated at ±10kV on driver and receiver pins
• Space-efficient design requiring only four small 0.1µF capacitors for the internal charge pump

Drivers, Receivers, Transceivers Applications

• Notebook computers
• Palmtop computers

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix CS indicates the commercial temperature range (0°C to 70°C). Confirm the package matches the 16-lead plastic SOIC narrow specification. Ensure the component is lead-free and RoHS compliant as per standard manufacturing practices. Cross-reference the manufacturer part number with official Analog Devices documentation to validate authenticity before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single 3.3V supply is available and ultra-low power consumption is critical. It is suitable for applications requiring EIA/TIA562 compliance with high noise immunity due to receiver hysteresis. Consider the 120kBaud maximum data rate and the requirement for external 0.1µF capacitors for the charge pump circuit during system design.

Drivers, Receivers, Transceivers Part Context

The LTC1386 belongs to the family of low-power RS232/EIA/TIA562 transceivers designed for battery-operated portable equipment. It serves as a pin-compatible alternative to the LT1181A while offering lower supply current. The device integrates a charge pump to generate the necessary positive and negative voltages from a single logic supply, simplifying the power architecture for mobile systems.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet lists the LT1780/LT1781, LTC1327, LTC1348, LTC1382, LTC1383, LTC1384, and LTC1385 as related parts. Verify voltage compatibility and feature sets such as shutdown modes or ESD ratings when considering these alternatives.
