ADM208EAR

Overview

The ADM208E is a robust RS-232 line driver and receiver family member operating from a single 5 V power supply. It features four drivers and four receivers with full-duplex communication capability. The device supports data rates up to 230 kbps and includes internal charge pumps requiring only four external 0.1 μF capacitors. It provides ±15 kV ESD protection on all I/O lines and complies with EMC directives. Operating temperature ranges from -40°C to +85°C, with a maximum supply voltage of 5.5 V and typical quiescent current of 13 mA.

Feature Summary

• Complies with EU EMC directive for low emissions and high immunity
• Provides ±15 kV ESD protection on all input and output lines
• Operates from a single 5 V power supply without external negative voltage generation components
• Includes internal pull-up and pull-down resistors on logic inputs

Applications

• Laptop computers
• Notebook computers
• Printers
• Peripherals
• Modems

Procurement Notes

Verify the specific package suffix (e.g., ARSZ for SSOP) against the design requirements. Confirm RoHS compliance status through official documentation. Ensure the ordering code matches the exact pin configuration and electrical specifications required for the target application circuit.

Selection Notes

Select this component when four independent RS-232 channels are required in a compact surface-mount package. It serves as a direct plug-in upgrade for older MAX2xxE designs. Choose this part for applications needing high ESD immunity and EMC compliance without shutdown control pins.

Part Context

The ADM208E belongs to the ADM2xxE family of ruggedized RS-232 transceivers. This family shares common architecture including internal charge pumps and ESD protection schemes. Variants like ADM206E and ADM213E differ in channel count or control features but maintain backward compatibility with previous generations.

Replacement Considerations

MAX208E is a functionally similar legacy part. Verify pinout compatibility before substitution. Check if the replacement meets the same EMC and ESD standards required by the original design specification.
