LTC2801CDE#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2801CDE#TRPBF is a single-channel RS-232 transceiver manufactured by Analog Devices Inc. It operates on a supply voltage range of 1.8V to 5.5V and features an integrated DC-to-DC converter that generates the necessary positive and negative voltages for RS-232 signaling, eliminating the need for external charge pumps. The device supports data rates up to 250kbps with a 1nF/3kΩ load and 100kbps with a standard 2.5nF/3kΩ TIA/EIA-232-F load. It is housed in a 12-lead, 4mm × 3mm plastic DFN package and is rated for commercial operating temperatures from 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates external components for generating RS-232 voltage levels
• Low-power shutdown mode reduces current consumption to 1µA for battery life extension
• Logic supply pin allows independent interfacing with various logic voltage levels
• High ESD protection rating of ±10kV on RS-232 interface pins

Drivers, Receivers, Transceivers Applications

• Battery-powered systems requiring low standby current
• Computers and consumer electronics with serial communication ports
• Diagnostic ports for industrial equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the 'C' grade designation corresponds to the required commercial temperature range of 0°C to 70°C for your application environment. Ensure compatibility with the 12-lead DFN footprint during PCB layout verification.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2801 variant specifically for applications requiring only one driver and one receiver. Consider the LTC2802 if higher data rates up to 1Mbps are necessary for smaller capacitive loads. Evaluate the power-saving modes, such as Receiver Active or Drivers Disabled, to optimize energy consumption based on the specific half-duplex or full-duplex requirements of the system design.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2801/LTC2802/LTC2803/LTC2804 family of low-power RS-232 transceivers. The family shares a common architecture featuring integrated DC-DC converters and flexible logic level shifting. The primary distinctions among members involve the number of drivers/receivers and maximum data rate capabilities, allowing designers to scale functionality while maintaining consistent interface characteristics.
