MAX4146EEE+

Overview

The MAX4146EEE+ is a differential line receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5V to 5.5V and supports data rates up to 20Mbps. The device features three receivers per package and includes an enable input for power management. It is housed in a 16-SSOP (QSOP) surface-mount package with a width of 3.90mm. The component functions reliably across an extended industrial temperature range from -40°C to +85°C, ensuring stable performance in demanding electronic applications.

Feature Summary

• Provides three independent differential line receivers in a single package
• Includes an active-low enable pin for efficient power control
• Supports high-speed data transmission up to 20Mbps
• Operates on a standard 5V supply voltage

Applications

• RS-422 communication interface circuits
• RS-485 bus transceiver systems
• Industrial process control networks
• Data acquisition systems requiring differential signaling

Procurement Notes

Verify the specific suffix 'EEE+' against the official datasheet to confirm the lead-free status and tape-and-reel or tube packaging configuration. Ensure the ordering part number matches the exact package dimensions and thermal characteristics required for your PCB layout. Cross-reference the manufacturer's latest documentation to confirm current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when designing systems that require multiple differential receivers within a limited board space. It is suitable for applications needing robust noise immunity and high-speed data integrity over twisted-pair cables. Consider the 16-pin QSOP footprint for compatibility with existing footprints. Evaluate the enable functionality if power conservation during idle states is a critical design requirement.

Part Context

This device belongs to the MAX4146 family of differential line receivers designed for high-speed serial communications. It complements driver components like the MAX483 to form complete transceiver solutions. The series is engineered for reliability in noisy environments, offering superior common-mode rejection compared to standard logic receivers. It serves as a key building block for robust industrial and commercial data links.

Replacement Considerations

The MAX4146EUE+ is a direct pin-compatible alternative in a smaller SSOP package. Verify voltage levels and enable logic polarity when substituting. Check datasheets for any differences in propagation delay or common-mode voltage ranges to ensure system compatibility.
