MAX3186CAP

Overview

The MAX3186CAP is a complete DCE RS-232 serial port designed for modem applications. It features five transmitters and three receivers without an internal charge pump, operating on dual supplies of +4.5V to +5.5V (VCC) and ±10.8V to ±13.2V (VDD/VSS). The device guarantees data rates up to 230kbps with supply currents under 300µA for IDD/ISS and 1mA for ICC. It provides enhanced ESD protection rated at ±15kV (Human Body Model), ±8kV (IEC Contact Discharge), and ±15kV (IEC Air-Gap Discharge). The component is housed in a 20-pin SSOP package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Enhanced electrostatic discharge protection on all transmitter outputs and receiver inputs
• Complete DCE serial port configuration optimized for modem integration
• Flow-through pinout architecture simplifies board layout

Applications

• Modems
• ISDN Modems
• Instruments meeting IEC1000-4-2 standards

Procurement Notes

Verify the specific suffix 'CAP' corresponds to the commercial temperature range and SSOP package when sourcing. Confirm that the ordering information matches the required voltage and environmental specifications for the target application environment.

Selection Notes

Select this component for designs requiring robust ESD immunity without external protection components. Ensure the system design accommodates the dual power supply requirements and the absence of an integrated charge pump for level shifting.

Part Context

This part belongs to the MAX3186 family of RS-232 transceivers manufactured by Maxim Integrated. It shares functional similarities with other devices in the series but is distinguished by its specific package type and guaranteed performance parameters for serial communication interfaces.

Replacement Considerations

Check for pin-compatible alternatives such as the MAX3186EAP for extended temperature ranges or other RS-232 transceivers from the same manufacturer if different packaging or thermal ratings are required.
