LTC2804IDHC#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2804IDHC#TRPBF is a dual RS-232 transceiver from Analog Devices, operating on a VCC supply of 1.8V to 5.5V with an independent VL logic supply. It features two drivers and two receivers, supporting data rates up to 1Mbps at 250pF/3kΩ loads. The device integrates a DC-to-DC converter generating ±7V and -6.3V rails for RS-232 signaling. Key electrical parameters include a typical shutdown current of 1µA and a receivers-active mode current of 15µA. Driver outputs withstand short circuits to ground or ±15V. The component is housed in a 16-lead (5mm × 3mm) plastic DFN package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates external charge pump capacitors
• Independent logic supply enables direct interfacing with various microprocessor voltage levels
• Low-power modes allow extended battery life through shutdown and receiver-active states
• High ESD protection rating ensures robustness against electrostatic discharge events

Drivers, Receivers, Transceivers Applications

• Battery-powered portable systems
• Computer diagnostic ports
• Consumer electronics interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging when sourcing this component. Confirm the temperature grade 'I' corresponds to the required industrial range of –40°C to 85°C for your application environment. Ensure the manufacturer designation matches Analog Devices Inc. to guarantee authenticity and compliance with the published specifications.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2804 over single-transceiver variants when dual communication channels are required within a compact footprint. Consider the DFN package dimensions if board space is constrained relative to SSOP alternatives. Verify that the load capacitance requirements align with the 1Mbps speed capability; higher capacitance loads will reduce the maximum achievable data rate according to the electrical characteristics table.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2801 family of low-voltage RS-232 transceivers. It shares architectural similarities with the LTC2801, LTC2802, and LTC2803 but provides dual driver/receiver functionality unlike the single-channel LTC2801/LTC2802. The IDHC suffix denotes the industrial temperature range and the 16-lead DFN package format, distinguishing it from the commercial grade CDHC variant.
