MAX3186CAP+

Overview

The MAX3186CAP+ is a complete DCE RS-232 serial port transceiver designed for modem applications. It features five RS-232 transmitters and three receivers, operating without an internal charge pump. The device supports data rates up to 230kbps with supply currents under 300µA for VCC/VSS and 1mA for VDD. It operates within a temperature range of 0°C to +70°C and utilizes a 20-pin SSOP package.

Feature Summary

• Enhanced ESD protection rated at ±15kV Human Body Model and ±8kV IEC1000-4-2 Contact Discharge
• Latchup-free operation during electrostatic discharge events
• Flow-through pinout architecture compatible with standard RS-232 interconnects

Applications

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

Procurement Notes

Verify the specific suffix CAP+ against official Analog Devices documentation to confirm the commercial temperature grade (0°C to +70°C) and SSOP-20 packaging configuration. Ensure compatibility with existing system voltage requirements before procurement.

Selection Notes

Select this component when designing systems requiring robust ESD immunity without external protection diodes. The absence of a charge pump makes it suitable for low-power applications where minimizing supply current is critical compared to standard RS-232 transceivers.

Part Context

This part belongs to the MAX3186 family of RS-232 interface ICs manufactured by Maxim Integrated, now part of Analog Devices. It serves as a specialized solution for serial communication ports in industrial and telecommunications equipment requiring high reliability.
