MAX3186EAP

Overview

The MAX3186EAP is a complete DCE RS-232 serial port transceiver designed for modem applications. It integrates five RS-232 transmitters and three RS-232 receivers without requiring an external charge pump. The device operates with VCC between +4.5V and +5.5V, VDD between +10.8V and +13.2V, and VSS between -10.8V and -13.2V. It guarantees data rates up to 230kbps with supply currents of less than 300µA for IDD and ISS, and less than 1mA for ICC. The component is housed in a 20-pin SSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• 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.
• Latchup-free operation during electrostatic discharge events.
• Flow-through pinout configuration compatible with standard RS-232 interconnecting cables.
• Complete DCE serial port solution optimized for modem applications.

Applications

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

Procurement Notes

Verify the specific suffix 'EAP' corresponds to the -40°C to +85°C temperature range and 20-pin SSOP package. Confirm that the ordering information matches the current manufacturer documentation, as product lines may undergo revisions or discontinuation. Ensure compatibility with existing system voltage requirements before procurement.

Selection Notes

Select this component when designing DCE RS-232 interfaces requiring high ESD immunity without charge pumps. It is suitable for systems needing five transmitter outputs and three receiver inputs. Verify that the board layout accommodates the 20-pin SSOP footprint and meets the required thermal dissipation limits for the specified operating temperature range.

Part Context

The MAX3186 series provides EMC-compliant RS-232 solutions for industrial and communication equipment. The EAP variant specifically denotes the extended temperature grade (-40°C to +85°C) packaged in a shrink small-outline package (SSOP). This distinguishes it from commercial grade variants and wide SO packages within the same functional family.

Replacement Considerations

Direct pin-compatible replacements include other MAX3186 variants such as MAX3186CWP or MAX3186EWP, provided the temperature range and package type match the design requirements. Cross-referencing datasheets is necessary to confirm identical electrical characteristics and pin assignments.
