LTC2802CDE#PBF

Drivers, Receivers, Transceivers Overview

The LTC2802CDE#PBF is a single-driver, single-receiver RS-232 transceiver manufactured by Analog Devices Inc. It operates on a supply voltage range of 1.8V to 5.5V and supports data rates up to 1Mbps with a 250pF/3kΩ load. The device features an integrated DC-to-DC converter generating VDD and VEE supplies for RS-232 levels. It includes low-power modes: Shutdown (1µA) and Receivers Active (15µA). The component is housed in a 12-lead DFN package measuring 4mm x 3mm and is rated for commercial temperatures from 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates external charge pump components
• Logic supply pin enables independent level shifting for various logic families
• Low-latency output enable facilitates half-duplex line sharing
• High ESD protection withstands ±10kV on RS-232 interface pins

Drivers, Receivers, Transceivers Applications

• Battery-powered systems requiring extended life
• Computers and consumer electronics interfaces
• Diagnostic ports for embedded devices

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the C grade corresponds to the 0°C to 70°C operating temperature range. Ensure the DE package designation matches the required 12-lead DFN footprint dimensions for PCB layout compatibility.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring a single full-duplex channel with high-speed operation up to 1Mbps. Choose the CDE variant when commercial temperature ranges are sufficient. Consider the IDE variant if industrial temperature ratings (-40°C to 85°C) are necessary for the deployment environment.

Drivers, Receivers, Transceivers Part Context

This component 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 its single-driver configuration compared to the dual-driver LTC2803/LTC2804, offering a compact solution for point-to-point serial communication links.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2802IDE#PBF offers identical electrical performance with an extended industrial temperature range. LTC2801CDE#PBF provides the same package and speed but lacks the 1Mbps capability under heavy loads.
