LTC2802IDE#PBF

Drivers, Receivers, Transceivers Overview

The LTC2802IDE#PBF is a single-driver, single-receiver RS-232 transceiver from Analog Devices. It operates on a VCC supply of 1.8V to 5.5V and features an integrated DC-to-DC converter generating ±7V and -6.3V rails for driver outputs. The device supports data rates up to 1Mbps with a 250pF/3kΩ load. It includes a separate VL logic supply pin (1.8V to 5.5V) for independent level shifting. Key electrical parameters include a typical VCC supply current of 2.3mA in normal mode, 1µA in shutdown, and 15µA in receivers-active mode. It provides ±10kV ESD protection on RS-232 interface pins and is housed in a 12-lead DFN package.

Drivers, Receivers, Transceivers Feature Summary

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

Drivers, Receivers, Transceivers Applications

• Battery-powered portable systems
• Diagnostic ports in industrial equipment
• Computer and consumer electronics interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when reviewing distributor listings. Confirm the IDE designation corresponds to the industrial temperature range of –40°C to +85°C. Ensure the ordering information matches the exact part number to avoid confusion with commercial grade or tape-and-reel variants.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring a single RS-232 channel with low power consumption. The 1Mbps data rate suits most standard serial communication needs. Consider the DFN-12 package size constraints during PCB layout. Verify that the system logic voltage aligns with the VL pin requirements for proper signal compatibility.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2801 family of RS-232 transceivers. It shares architectural similarities with the LTC2801, LTC2803, and LTC2804 models. The primary distinction lies in the number of drivers and receivers provided. This specific model offers one driver and one receiver configuration within the same compact footprint family.
