LTC2804IDHC#PBF

Drivers, Receivers, Transceivers Overview

The LTC2804IDHC#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 (5mm × 3mm) plastic DFN package. The device supports data rates up to 1Mbps under specific load conditions. Key electrical parameters include a typical VCC supply current of 2.3mA in normal mode and a shutdown current of 1µA. It features an internal DC-to-DC converter generating ±7V and -6.3V rails, ESD protection rated at ±10kV, and operates within a temperature range of –40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates the need for external charge pumps or positive/negative voltage generators.
• Logic supply pin allows independent interfacing with various logic levels regardless of the main supply voltage.
• Low-power modes enable extended battery life through shutdown and receiver-active states.
• Robust driver outputs are protected against short circuits and overload without damage.

Drivers, Receivers, Transceivers Applications

• Battery-powered systems requiring direct operation from alkaline or NiMH cells
• Computers and consumer electronics with UART interfaces
• Diagnostic ports in industrial equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix #PBF indicates lead-free finish and RoHS compliance. Confirm the 'I' grade designation matches the required –40°C to +85°C operating temperature range. Ensure the DHC package footprint aligns with the PCB layout specifications provided in the datasheet.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring dual RS-232 channels with high-speed operation up to 1Mbps. Compare against the LTC2803 if only 250kbps speed is sufficient, as it may offer different power characteristics. Ensure the system logic voltage falls within the 1.8V to 5.5V range compatible with the VL pin.

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 LTC2803 but offers higher data rate capabilities. The family is designed for low-voltage, low-power serial communication interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2803CDHC#PBF: Dual RS-232 transceiver with lower maximum data rate of 250kbps. LTC2804CGN-1#PBF: Alternative SSOP-16 package version with identical electrical performance.
