Overview
The MAX3226EEAE is a single-driver, single-receiver RS-232 transceiver from the MAX3226E series. It operates on a +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 ±15kV ESD protection on all I/O pins and utilizes a dual charge pump requiring only four 0.1μF capacitors. The component is housed in a 16-pin SSOP package and supports an operating temperature range of -40°C to +85°C.
Feature Summary
- AutoShutdown Plus functionality automatically reduces power consumption by shutting down internal charge pumps during periods of inactivity.
- Integrated dual charge pump generates required RS-232 voltage levels using minimal external capacitance.
- Enhanced electrostatic discharge protection ensures robustness against high-voltage static events.
Applications
- Notebook, subnotebook, and palmtop computers
- Cellular phones and battery-powered equipment
- Hand-held devices and peripherals
Procurement Notes
Verify the specific ordering suffix to confirm the package type and temperature rating. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement.
Selection Notes
Select this model for applications requiring a single full-duplex channel with low standby power. Ensure the system design accommodates the 250kbps maximum data rate requirement rather than higher-speed alternatives.
Part Context
This component belongs to the MAX3224E/MAX3225E/MAX3226E/MAX3227E family. These devices share common features such as AutoShutdown Plus and ESD protection but differ in driver/receiver counts and guaranteed data rates.
Replacement Considerations
MAX3224EEAE (2 drivers/2 receivers)
FAQ
How does the AutoShutdown Plus feature function?
It monitors receiver and transmitter inputs. If no valid signal transition occurs for more than 30 seconds, the device shuts down the charge pumps to achieve 1μA supply current. It wakes up upon detecting a valid transition.
What is the purpose of the READY output pin?
The READY output asserts high when the internal charge pumps are regulating and the device has reached the necessary voltage levels to begin transmitting RS-232 signals.
