MAX3225EUP/V+

Overview

The MAX3225EUP/V+ is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a TSSOP-20 surface-mount package. It supports data rates up to 1 Mbps and operates within a supply voltage range of 3.0 V to 5.5 V. The device integrates two drivers and two receivers for full-duplex communication. Key electrical specifications include a maximum operating supply current of 1 mA and an ESD protection rating of 15 kV. The component features an AutoShutdown Plus function to reduce power consumption during idle periods.

Feature Summary

• Integrates AutoShutdown Plus functionality to minimize power usage when no valid signal is present on the RS-232 bus.

Applications

• Industrial control systems requiring robust serial communication interfaces
• Portable battery-powered equipment utilizing low-power RS-232 links
• Embedded systems with limited power budgets needing efficient interface solutions

Procurement Notes

Verify the specific suffix 'V+' against official manufacturer documentation to confirm compliance with RoHS directives and lead-free manufacturing standards. Confirm that the TSSOP-20 package matches the target PCB footprint requirements. Ensure the selected variant aligns with the required temperature range and functional specifications for the intended application environment.

Selection Notes

Select this component when a dual-channel RS-232 solution with integrated charge pumps and low quiescent current is required. The TSSOP-20 package offers a compact form factor suitable for space-constrained designs. Verify compatibility with the system's logic levels and ensure adequate decoupling capacitance is available for the internal charge pump operation.

Part Context

This part belongs to the MAX3225 series of RS-232 transceivers designed for high-speed communication. The series is characterized by its ability to operate from a single power supply while generating the necessary positive and negative voltages for RS-232 signaling. The MAX3225EUP/V+ specifically targets applications demanding reliability and low power consumption in a small outline package.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements may differ in pinout or electrical characteristics. Validate any alternative component against the original datasheet specifications before implementation.
