MAX3225EUP/V+T

Overview

The MAX3225EUP/V+T is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 1Mbps. The device features two drivers and two receivers for full-duplex communication. It incorporates AutoShutdown Plus technology, which automatically places the device in a low-power shutdown mode when the RS-232 transmitter is idle or the power supply is removed. This functionality reduces quiescent current consumption significantly during periods of inactivity.

Feature Summary

• AutoShutdown Plus technology enables automatic low-power state activation upon transmitter idling or power loss
• Integrated charge pump eliminates the need for external capacitors for internal voltage generation
• Provides robust ESD protection rated at 15kV on all pins

Applications

• Industrial control systems requiring reliable serial communication
• Portable instrumentation with battery power constraints
• Modem and fax machine interface circuits

Procurement Notes

Verify the specific suffix 'V' against official manufacturer documentation to confirm temperature grade and package variations. Confirm RoHS compliance status through the latest datasheet revision. Ensure the ordering part number matches the required tape-and-reel packaging format for surface-mount assembly processes.

Selection Notes

Select this component for applications requiring dual-channel RS-232 connectivity with minimal standby power consumption. The integrated charge pump simplifies board layout by reducing external component count. Verify that the operating temperature range aligns with the system environment requirements before finalizing the design.

Part Context

This part belongs to the MAX3225 family of single-supply RS-232 transceivers. It shares functional similarities with other Maxim Integrated devices like the MAX3232 but offers specific power management features tailored for portable electronics. The family is designed to meet industry standards for serial communication interfaces.

Replacement Considerations

Direct replacements include the MAX3225EUP+ and MAX3225EUE+. Verify pin compatibility and electrical specifications before substitution.
