MAX3223ECPP+

Overview

The MAX3223ECPP+ is a dual-driver, dual-receiver RS-232 transceiver in a 20-pin PDIP package. It operates from a +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 on all I/O pins and utilizes a dual charge pump requiring four 0.1µF capacitors.

Feature Summary

• AutoShutdown technology for ultra-low power consumption
• Robust ±15kV electrostatic discharge protection
• True RS-232 performance from low-voltage supplies

Applications

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

Procurement Notes

Verify the specific suffix 'CPP+' corresponds to the 20-pin Plastic DIP package with a commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering code matches the exact manufacturer part number to avoid pinout or electrical specification mismatches during procurement.

Selection Notes

Select this component for applications requiring full-duplex RS-232 communication with minimal power consumption. The 20-pin PDIP package is suitable for through-hole mounting. Verify that the system requires two drivers and two receivers, as other variants like the MAX3221E offer single-channel configurations.

Part Context

This part belongs to the MAX3221E/MAX3223E/MAX3243E family of 3V-powered RS-232 transceivers. It shares core features such as the AutoShutdown circuit and high ESD protection with its siblings, differing primarily in the number of drivers and receivers provided within the same functional architecture.
