Overview
The MAX3223EEUP+T is a true RS-232 transceiver from the MAX3221E/MAX3223E/MAX3243E family, manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers in a 20-pin TSSOP package with an operating temperature range of -40°C to +85°C. The device operates on a single +3.0V to +5.5V supply and achieves a typical supply current of 1µA through AutoShutdown technology. It supports data rates up to 250kbps and includes enhanced ESD protection rated at ±15kV (Human Body Model) and ±8kV (IEC 1000-4-2 Contact Discharge).
Feature Summary
- AutoShutdown technology reduces supply current to 1µA when no valid RS-232 signal levels are detected.
- Integrated dual charge pump generates required voltage levels without external inductors.
- Enhanced electrostatic discharge protection on all transmitter outputs and receiver inputs.
Applications
- Notebook, subnotebook, and palmtop computers
- Cellular phones and handheld equipment
- Battery-powered peripherals and printers
Procurement Notes
Verify the specific suffix EEUP+T corresponds to the 20-pin TSSOP package and industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status for lead-free manufacturing requirements. Ensure the ordering code matches the exact manufacturer part number to avoid pinout or functional discrepancies.
Selection Notes
Select this component for applications requiring low power consumption during idle states via automatic shutdown. Choose the MAX3223 variant specifically when two independent transmit and receive channels are necessary. Verify that the system operates within the +3.0V to +5.5V supply voltage range and requires standard RS-232 signaling levels.
Part Context
This part belongs to the MAX3221E/MAX3223E/MAX3243E series of 3V-powered RS-232 transceivers. The MAX3223E specifically provides two drivers and two receivers, distinguishing it from the single-channel MAX3221E and the multi-channel MAX3243E. All variants share the same core AutoShutdown and ESD protection technologies.
Replacement Considerations
Direct substitutes within the same family include MAX3223ECAP+T (SSOP package) and MAX3223ECTP+T (TQFN package), provided the package footprint is adaptable. Cross-family replacements require verification of driver/receiver counts and voltage compatibility.
