LTC2801CDE#PBF

Drivers, Receivers, Transceivers Overview

The LTC2801CDE#PBF is a single-driver, single-receiver RS-232 transceiver from Analog Devices. It operates on a VCC supply of 1.8V to 5.5V and features an integrated DC-to-DC converter generating ±7V and -6.3V rails for driver outputs. The device supports data rates up to 250kbps with a 1nF/3kΩ load and 100kbps with a 2.5nF/3kΩ TIA/EIA-232-F load. It includes a separate VL logic supply pin for level shifting. Key power modes include Shutdown (1µA) and Receivers Active (15µA). It is housed in a 12-lead DFN package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates external charge pump components
• Independent logic supply allows direct interfacing with various microprocessor voltage levels
• Low-power shutdown mode extends battery life in portable applications
• High ESD protection rating on RS-232 interface pins

Drivers, Receivers, Transceivers Applications

• Battery-powered systems requiring low quiescent current
• Diagnostic ports in industrial equipment
• Consumer electronics with limited board space

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering samples or small quantities. Confirm the CDE suffix corresponds to the commercial temperature range and DFN-12 package. Ensure the component source provides valid traceability documentation for quality assurance purposes.

Drivers, Receivers, Transceivers Selection Notes

Select this part for single-channel RS-232 communication where power efficiency is critical. Compare against the LTC2802 if higher data rates are required. Consider the LTC2803 family if dual channels are needed. Verify that the external inductor selection meets saturation current requirements for the application.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2801/LTC2802/LTC2803/LTC2804 family of low-power RS-232 transceivers. It shares architectural similarities with the LTC2802 but offers lower maximum data rates. The family is designed for applications requiring minimal external components and flexible power supply configurations.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2802CDE#PBF offers identical packaging and functionality with increased data rate capability. LTC2801IDE#PBF provides the same electrical characteristics but with an extended industrial temperature range.
