MAX3182EUK

Overview

The MAX3182EUK is a single RS-232 line receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +3V to +5.5V and supports data rates up to 1.5Mbps. The device features Schmitt-trigger inputs for noise immunity and provides 15kV ESD protection on all pins. It is housed in a compact SOT-23-5 surface-mount package and functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates 15kV human-body model ESD protection directly on the receiver input pin.
• Utilizes Schmitt-trigger input circuitry to filter noise and ensure clean signal transitions.
• Designed for low-power operation with minimal quiescent current consumption.

Applications

• Portable battery-powered equipment requiring serial communication
• Industrial control systems with noisy environments
• Embedded systems utilizing RS-232 interfaces

Procurement Notes

Verify the specific suffix 'EUK' against official manufacturer documentation to confirm the SOT-23-5 package and tape-and-reel orientation. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Selection Notes

Select this component when a single RS-232 receiver is needed in a small footprint. It is suitable for designs operating between 3V and 5.5V where high ESD robustness is critical. Compare against the MAX3181 if ESD protection is not required, or the MAX3188 if transmission capability is also needed.

Part Context

This part belongs to the Maxim Integrated MAX318x family of RS-232 interface devices. These components are designed to provide reliable serial communication in space-constrained applications. The MAX3182 specifically addresses the receiving end of the link, complementing drivers like the MAX3188.

Replacement Considerations

The MAX3181EUK serves as a compatible alternative lacking integrated ESD protection. For full transceiver functionality, consider the MAX3188EEUT. Verify pin compatibility and electrical characteristics against the original design requirements before substitution.
