LTC2804CDHC#PBF

Drivers, Receivers, Transceivers Overview

The LTC2804CDHC#PBF 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 DFN package (5mm x 3mm). The device supports data rates up to 1Mbps with a 250pF/3kΩ load. It features low-power modes including 1µA shutdown and 15µA receiver-active states. An internal DC-to-DC converter generates the necessary voltages for RS-232 signaling. The component provides ESD protection rated at ±10kV and includes driver outputs protected against short circuits.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates external charge pump capacitors
• Low-power operation with shutdown and receiver-active modes
• High ESD protection on RS-232 interface pins
• Logic supply pin allows independent level shifting

Drivers, Receivers, Transceivers Applications

• Battery-powered systems
• Computers and consumer electronics
• Diagnostic ports

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and RoHS compliance as per manufacturer standards. Confirm the package type matches the required PCB footprint. Ensure the temperature grade corresponds to the application environment requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring dual RS-232 channels in a compact footprint. The 1Mbps data rate suits high-speed serial communication needs. Consider the separate logic supply pin if interfacing with microprocessors operating at different voltage levels than the main power supply.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2801 family of single and dual RS-232 transceivers. It shares architectural similarities with the LTC2801, LTC2802, and LTC2803 models but offers dual drivers and higher speed capabilities compared to the single-channel variants.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include LTC2804IDHC#PBF for extended temperature ranges.
