LTC2804CDHC#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2804CDHC#TRPBF is a dual RS-232 transceiver manufactured by Analog Devices Inc. It operates on a supply voltage range of 1.8V to 5.5V and features two drivers and two receivers. The maximum data rate is 1Mbps with a 250pF/3kΩ load, 250kbps with a 1nF/3kΩ load, and 100kbps with a 2.5nF/3kΩ load. It utilizes an integrated DC-to-DC converter for RS-232 level generation. The device is housed in a 16-lead (5mm × 3mm) plastic DFN package (DHC). Operating temperature range is 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter generates power supplies for driving RS-232 levels without external charge pumps.
• Logic supply pin allows easy interfacing with different logic levels independent of the DC-DC supply.
• Low-power modes include shutdown current of 1µA and receiver-active mode current of 15µA.
• Driver outputs are protected from overload and can be shorted to ground or up to ±15V without damage.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact specification required for your design. Check for RoHS compliance status as indicated in official documentation. Validate that the package type corresponds to the 16-lead DHC format.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2804CDHC#TRPBF for applications requiring dual RS-232 channels with high-speed operation up to 1Mbps. Consider the 1.8V to 5.5V supply range for compatibility with various logic families. Evaluate the low-power modes if battery life is a critical constraint. Ensure the thermal performance of the DFN package meets the system requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2801/LTC2802/LTC2803/LTC2804 family of single and dual RS-232 transceivers. These devices are designed for narrow SSOP and chip-scale DFN packages. They operate directly from two alkaline, NiCd, or NiMH cells due to their wide supply voltage range.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2803CDHC#TRPBF offers similar functionality but supports a lower maximum data rate of 250kbps compared to the 1Mbps capability of the LTC2804.
