LTC2803CDHC#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2803CDHC#TRPBF is a dual RS-232 transceiver from Analog Devices Inc., operating within a supply voltage range of 1.8V to 5.5V. It integrates two drivers and two receivers, supporting data rates up to 250kbps for standard TIA/EIA-232-F loads (RL=3kΩ, CL=2.5nF). The device utilizes an internal DC-to-DC converter to generate the necessary positive and negative voltages for RS-232 signaling. It features low-power modes including Shutdown (1µA) and Receivers Active (15µA), and provides ESD protection rated at ±10kV on the interface pins. The component is housed in a 16-lead DFN package with commercial temperature ratings.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates external charge pump components
• Low-power operation with shutdown current as low as 1µA
• High ESD protection rating of ±10kV on RS-232 interface lines
• Independent logic supply pin allows level shifting between different voltage domains

Drivers, Receivers, Transceivers Applications

• Battery-powered portable systems
• Diagnostic ports in industrial equipment
• Consumer electronics with UART interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging configuration. Confirm that the CDHC variant corresponds to the commercial temperature grade (0°C to 70°C) rather than the extended industrial grade. Ensure compatibility with required PCB footprint dimensions for the 16-lead DFN package before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this part when a dual-channel RS-232 solution is required with minimal external component count. The LTC2803 supports lower data rates compared to the LTC2804; verify if 250kbps meets system timing requirements. Consider the DFN package thermal characteristics and ensure adequate copper area for the exposed pad to manage heat dissipation effectively during continuous operation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2801/LTC2802/LTC2803/LTC2804 family of single and dual RS-232 transceivers. It shares architectural similarities with the LTC2804 but offers reduced maximum data rates suitable for slower communication links. The family emphasizes low power consumption and small form factors for modern embedded applications.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2803IDHC#TRPBF serves as the industrial temperature grade equivalent. For higher speed requirements, the LTC2804CDHC#TRPBF provides 1Mbps capability in the same package.
