LTC2803IDHC#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2803IDHC#TRPBF is a dual RS-232 transceiver from Analog Devices, operating on a supply voltage range of 1.8V to 5.5V. It integrates two drivers and two receivers within a 16-lead (5mm × 3mm) plastic DFN package. The device supports maximum data rates of 250kbps for loads up to 1nF/3kΩ and 100kbps for standard TIA/EIA-232-F loads of 2.5nF/3kΩ. An internal DC-to-DC converter generates the necessary positive and negative supplies for RS-232 signaling. Key electrical characteristics include a typical VCC supply current of 2.3mA in normal mode, 1µA in shutdown, and 15µA with receivers active. The component features ±10kV ESD protection on the RS-232 interface and operates over an industrial temperature range of -40°C to 85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates external charge pump components
• Logic supply pin enables independent level shifting for various microprocessor interfaces
• Low-power modes including shutdown and receiver-active states extend battery life
• High ESD protection rating ensures robustness against electrostatic discharge events

Drivers, Receivers, Transceivers Applications

• Battery-powered portable systems requiring low quiescent current
• Industrial diagnostic ports and communication equipment
• Consumer electronics interfacing with UART or microprocessors

Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific ordering suffix #TRPBF corresponds to tape and reel packaging rather than tube packaging when sourcing this component. Confirm the manufacturer designation as Analog Devices Inc. matches your supply chain requirements. Ensure the part number includes the correct temperature grade identifier for the intended operational environment.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2803IDHC#TRPBF when a dual-channel RS-232 solution is required in a compact surface-mount footprint. This part is suitable for designs needing independent logic voltage levels separate from the main supply rail. Consider the thermal performance of the exposed pad DFN package during PCB layout to ensure reliable operation under continuous load conditions.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2801 family of single and dual RS-232 transceivers manufactured by Analog Devices. The family shares a common architecture featuring integrated power generation and low-power management modes. The IDHC suffix indicates the industrial temperature grade (-40°C to 85°C) and the specific 16-lead DFN package configuration used for space-constrained applications.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2803CDHC#TRPBF serves as a commercial grade alternative with identical electrical specifications but a limited operating temperature range of 0°C to 70°C. Verify that the ambient temperature conditions of the target application remain within the commercial range before substituting.
