ADM2209EARUZ-REEL7

Overview

The ADM2209EARUZ-REEL7 is a dual-port RS-232 transceiver in a 38-lead TSSOP package. It integrates six drivers and ten receivers, operating from a single +12 V supply via an onboard charge pump that eliminates the need for a negative voltage rail. The device supports data rates up to 460 kbps under standard loads and up to 920 kbps with reduced capacitance. Standby mode is managed by a separate V_STBY supply (3.3 V or 5 V), keeping one receiver per port active for system wake-up while reducing current consumption to less than 200 mA.

Feature Summary

• Integrates two complete serial ports with six drivers and ten receivers on a single chip
• Generates a negative supply rail internally using a charge pump, requiring only a single positive power source
• Features a dedicated standby supply pin that maintains one receiver per port active for peripheral monitoring and system wake-up
• Includes robust transient protection circuits on all I/O lines to withstand electrostatic discharge and electrical fast transients

Applications

• Desktop and portable personal computers
• Printers and peripherals
• Modems

Procurement Notes

Verify the component matches the specific Analog Devices part number ADM2209EARUZ-REEL7. Confirm the package type is 38-lead TSSOP and the temperature range is industrial (-40°C to +85°C). Ensure the datasheet revision aligns with the required specifications for your design.

Selection Notes

Select this component when a single-chip solution for dual RS-232 ports is required without external negative voltage supplies. It is suitable for applications needing high ESD and EFT immunity. Consider the 38-lead TSSOP footprint and the requirement for external 0.1 mF charge pump capacitors during the PCB layout phase.

Part Context

This component belongs to the ADM2209E series of rugged dual-port RS-232 line drivers/receivers manufactured by Analog Devices. It is designed to replace traditional multi-component solutions by integrating the necessary logic conversion and voltage inversion onto one die, simplifying board space requirements for standard serial interfaces.
