MAX3182EUK+

Overview

The MAX3182EUK+ is a single RS-232 receiver integrated circuit 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 15kV ESD protection on the input pins, enhancing reliability in harsh environments. It draws a typical operating supply current of 5uA, making it suitable for low-power applications. The component is housed in a compact SOT-23-5 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides high-speed serial data reception with support for 1.5Mbps transmission rates.
• Integrates robust electrostatic discharge protection rated at 15kV on input lines.
• Designed for ultra-low power consumption with minimal quiescent current draw.

Applications

• Portable battery-powered equipment requiring serial communication interfaces
• Industrial control systems operating in electrically noisy environments
• Embedded devices utilizing RS-232 protocols for data transmission

Procurement Notes

Verify the specific suffix and tape-and-reel configuration when ordering, as packaging variations exist within the product line. Confirm that the required ESD protection level aligns with system design specifications. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Selection Notes

Select this component when a single-channel RS-232 receiver is needed without transmitter functionality. Compare against the MAX3180 variant if ESD protection is not required for the specific application environment. Consider the SOT-23-5 package constraints regarding thermal dissipation and board space. Verify that the 1.5Mbps speed meets the maximum baud rate requirements of the connected serial devices.

Part Context

This part belongs to the MAX3182 family of RS-232 interface components designed for low-voltage operation. It serves as a complementary receiver-only solution within Maxim's broader portfolio of serial communication ICs. The device addresses the need for compact, energy-efficient signal conditioning in modern portable electronics.

Replacement Considerations

The MAX3180EUK+T is a verified substitute offering identical electrical performance but lacks the 15kV ESD protection feature found in the MAX3182EUK+. Designers must evaluate whether the reduced protection level is acceptable for their specific environmental conditions before swapping these parts.
