Overview
The MAX3224EEUP+T is a dual RS-232 transceiver manufactured by Analog Devices (Maxim Integrated). It operates on a single +3.0V to +5.5V supply and guarantees a data rate of 250kbps. The device features AutoShutdown Plus technology, reducing supply current to 1μA when idle. It includes two drivers and two receivers with ±15kV ESD protection. The component is housed in a 20-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- AutoShutdown Plus functionality automatically reduces power consumption during periods of inactivity
- Integrated dual charge pump generates required voltage levels without external transformers
- Enhanced electrostatic discharge protection on all inputs and outputs for robust operation
Applications
- Notebook, subnotebook, and palmtop computers
- Cellular phones and battery-powered equipment
- Hand-held devices and peripherals such as printers
Procurement Notes
Verify the specific suffix EEUP against official documentation to confirm the 20-pin TSSOP package and industrial temperature rating. Confirm lead-free status via RoHS compliance markings. Ensure ordering quantities match distributor reel or tube specifications. Validate that the manufacturer designation matches Analog Devices Inc. or Maxim Integrated to avoid counterfeit components.
Selection Notes
Select this part for applications requiring low standby power and high ESD tolerance. The 250kbps data rate suits standard serial communication needs. Consider the MAX3225E variant if 1Mbps speeds are necessary. Verify that the 20-pin TSSOP footprint fits the PCB layout constraints. Ensure the system voltage remains within the 3.0V to 5.5V operational range.
Part Context
This component belongs to the MAX3224E family of RS-232 transceivers designed for portable electronics. It shares core architecture with the MAX3225E, MAX3226E, and MAX3227E models. The primary distinction lies in the guaranteed data rate and driver/receiver count compared to other members of the series. It utilizes Maxim's proprietary AutoShutdown Plus technology for power management.
Replacement Considerations
The MAX3225EEUP+ offers identical pinout and packaging but guarantees 1Mbps operation instead of 250kbps. The MAX3224ECUP+ provides the same electrical performance in a commercial temperature range (0°C to +70°C) rather than the extended industrial range.
