MAX3223EEAP+T

Overview

The MAX3223EEAP+T is a dual-driver, dual-receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. 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 ±15kV ESD protection for transmitter outputs and receiver inputs. The component is housed in a 20-pin SSOP package and functions 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 pumps generate internal voltage levels from a single low-voltage supply without external transformers.
• Enhanced electrostatic discharge protection ensures robust operation 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 EEAP+T to confirm the 20-pin SSOP package and industrial temperature rating (-40°C to +85°C). Ensure compatibility with the required footprint and thermal management specifications for the target PCB design before finalizing procurement.

Selection Notes

Select this component for applications requiring low-power standby modes and reliable communication over standard RS-232 cables. It is suitable for systems where space constraints limit the use of larger packages or where battery life is a critical design parameter.

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 for balanced full-duplex communication needs.
