MAX3223ECAP+T

Overview

The MAX3223ECAP+T is a dual-driver, dual-receiver RS-232 transceiver in a 20-pin SSOP package. It operates from a single +3.0V to +5.5V supply and achieves 1µA supply current via the AutoShutdown feature when no valid signal is detected on receiver inputs for 30µs. The device supports data rates up to 235kbps with typical loads of 3kΩ parallel 1000pF. It utilizes internal charge pumps requiring only 0.1µF capacitors for 3.3V operation. The operating temperature range is -40°C to +85°C.

Feature Summary

• AutoShutdown functionality reduces power consumption by disabling onboard power supplies and drivers upon detecting invalid receiver input levels.

Applications

• Battery-powered equipment
• Hand-held equipment
• Portable diagnostics equipment

Procurement Notes

Verify that the ordering suffix 'T' corresponds to tape-and-reel packaging as specified in official manufacturer documentation. Confirm the component meets RoHS compliance standards before procurement. Ensure the specific package variant matches the required footprint for the target PCB design.

Selection Notes

Select this component for applications requiring low-power standby modes in portable devices. Verify compatibility with the system's logic voltage levels, as it interfaces directly with 3.3V and 5V CMOS families. Ensure adequate decoupling capacitors are available to support the internal charge pump requirements.

Part Context

This part belongs to the MAX3221/MAX3223/MAX3243 family of 3V-powered RS-232 transceivers. It shares core features like AutoShutdown and integrated charge pumps with siblings such as the MAX3221 (single driver) and MAX3243 (three drivers). The ECAP designation indicates a specific commercial/extended temperature grade within the SSOP package lineup.
