MAX3223EEAP+G071

Overview

The MAX3223EEAP+G071 is a dual-driver, dual-receiver RS-232 transceiver from the MAX3223E series. It operates on a single +3.0V to +5.5V supply and supports data rates up to 250kbps. The device features an AutoShutdown function that reduces supply current to 1µA when no valid signal is detected. It includes a dual charge pump requiring four 0.1µF capacitors for operation. ESD protection is rated at ±15kV (Human Body Model), ±8kV (Contact Discharge), and ±15kV (Air-Gap). The component is housed in a 20-pin SSOP package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• AutoShutdown technology automatically disables the charge pump and drivers to minimize power consumption during idle periods.
• Integrated dual charge pump generates internal voltage rails without external transformers or inductors.
• Enhanced electrostatic discharge protection ensures robustness against high-voltage static events.

Applications

• Notebook, subnotebook, and palmtop computers
• Battery-powered equipment and handheld devices
• Cellular phones and peripherals

Procurement Notes

Verify the specific ordering suffix G071 against official manufacturer documentation to confirm exact packaging and lot traceability details. Confirm availability status as distribution channels may list this part as discontinued or limited stock. Ensure compliance with RoHS directives by checking the lead-free designation indicated by the plus sign in the part number.

Selection Notes

Select this component for applications requiring low-power RS-232 communication in space-constrained designs. The 20-pin SSOP package suits surface-mount assembly processes. Consider the 250kbps speed limit and 1µA shutdown current as key differentiators for battery-operated systems compared to standard non-shutdown transceivers.

Part Context

This part belongs to the MAX3221E/MAX3223E/MAX3243E family of 3V-powered RS-232 transceivers. While the MAX3221E offers one driver/receiver and the MAX3243E provides three drivers and five receivers, the MAX3223E specifically provides two drivers and two receivers. All variants share the same core AutoShutdown and ESD protection technologies.

Replacement Considerations

Direct functional substitutes within the same family include the MAX3223ECAP+ (SSOP, 0°C to +70°C) and MAX3223EEUP+ (TSSOP, -40°C to +85°C). Verify pin compatibility and thermal grade requirements before substitution.
