MAX3223CAP+G65

Overview

The MAX3223CAP+G65 is a dual-driver, dual-receiver RS-232 transceiver from the MAX3223 family. It operates on a single +3.0V to +5.5V supply and features AutoShutdown technology that reduces supply current to 1µA when no valid signal is detected on receiver inputs for 30µs. The device guarantees a 120kbps data rate with worst-case loads of 3kΩ in parallel with 1000pF, though typical operation supports up to 235kbps. It utilizes internal dual charge pumps requiring only 0.1µF capacitors for 3.3V operation. The component is housed in a 20-pin SSOP package and is rated for an operating temperature range of 0°C to +70°C.

Feature Summary

• AutoShutdown functionality automatically disables onboard power supplies and drivers upon detecting invalid signal levels, significantly reducing power consumption.
• Integrated dual charge pump circuitry generates required voltage levels without needing external ±12V supplies.
• Provides full-duplex communication capability with two independent drivers and receivers.

Applications

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

Procurement Notes

Verify the specific suffix G65 against official manufacturer documentation to confirm its exact meaning regarding packaging or testing variations. Confirm availability status as distributor records may indicate discontinuation or limited stock. Ensure the ordering information matches the required 20-pin SSOP package and commercial temperature range specifications.

Selection Notes

Select this component for applications requiring low-power RS-232 communication from a single 3V or 5V supply. It is suitable where minimizing standby current is critical due to the AutoShutdown feature. Compare against MAX3221 (single driver) or MAX3243 (three drivers) if channel count requirements differ. Verify capacitor values align with the specific VCC voltage used in the design.

Part Context

This part belongs to the MAX3221/MAX3223/MAX3243 family of 3V-powered EIA/TIA-232 transceivers. The MAX3223 specifically provides two drivers and two receivers in a 20-pin package. It shares core technologies like AutoShutdown and low-capacitor requirements with the MAX3221 and MAX3243 variants within the same datasheet.
