LTC2802IDE#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2802IDE#TRPBF is a single-driver, single-receiver RS-232 transceiver manufactured by Analog Devices. It operates on a VCC supply range of 1.8V to 5.5V and features an integrated DC-to-DC converter generating ±7V and -6.3V rails. The device supports data rates up to 1Mbps with a 250pF/3kΩ load. It includes a separate VL logic supply pin for 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. The component is housed in a 12-lead DFN package (4mm × 3mm) and is rated for an operating temperature range of –40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated DC-to-DC converter eliminates external charge pump components
• Independent logic supply allows interface with varying logic levels
• Low-power modes extend battery life in portable applications
• High ESD protection on RS-232 interface pins

Drivers, Receivers, Transceivers Applications

• Battery-powered systems requiring low standby current
• Computers and consumer electronics with serial ports
• Diagnostic ports for industrial equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IDE designation corresponds to the industrial temperature grade (-40°C to +85°C). Ensure the order matches the single-driver configuration required for the design. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring a single RS-232 channel with high-speed operation up to 1Mbps. It is suitable for systems powered by two alkaline or NiMH cells due to the wide input voltage range. Consider the DFN-12 package size for space-constrained layouts. Verify that the external inductor and capacitor values meet the minimum requirements for the internal switching regulator stability.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2801 family of RS-232 transceivers. It shares architectural similarities with the LTC2801 but offers higher data rate capabilities. The family includes dual-channel variants like the LTC2804. All members utilize the same core switching regulator topology and power-saving control schemes.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC2801CDE#TRPBF serves as a functional substitute if lower data rates are acceptable. The LTC2804IDE#TRPBF provides additional channels in the same package footprint. Verify pin compatibility and thermal performance when substituting within the family.
