MAX3186CWP+T

Overview

The MAX3186CWP+T is a complete DCE RS-232 serial port integrated circuit designed for modem applications. It features five RS-232 transmitters and three RS-232 receivers, operating without an internal charge pump. The device guarantees data rates up to 230kbps and provides enhanced ESD protection rated at ±15kV (Human Body Model), ±8kV (IEC 1000-4-2 Contact Discharge), and ±15kV (IEC 1000-4-2 Air-Gap Discharge). It operates on dual power supplies: VCC from +4.5V to +5.5V, and VDD/VSS ranging from +10.8V to +13.2V and -10.8V to -13.2V respectively. The component is housed in a 20-pin Wide SO package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated flow-through pinout architecture providing a complete DCE serial port solution
• Robust electrostatic discharge protection ensuring latchup-free operation during ESD events
• Elimination of external charge pump components through optimized driver design

Applications

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

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the '+T' designation aligns with the manufacturer's current tape-and-reel packaging specifications. Ensure compatibility with standard 20-pin Wide SO footprint dimensions before finalizing procurement orders.

Selection Notes

Select this component when designing equipment requiring compliance with stringent European ESD requirements. It is suitable for systems needing multiple transmitter and receiver channels without the complexity of charge pumps. Verify that the application environment remains within the specified 0°C to +70°C operational limits.

Part Context

This part belongs to the MAX3186 family of RS-232 interface ICs manufactured by Maxim Integrated. It serves as a specialized serial port controller tailored for communication hardware. The device distinguishes itself by integrating high-voltage drivers and robust protection structures into a single compact package.

Replacement Considerations

Consider the MAX3186EWP for extended industrial temperature ranges (-40°C to +85°C). Evaluate the MAX3186CAP or MAX3186EAP if a 20-pin SSOP package is required instead of the Wide SO format.
