MAX3223EAP+

Overview

The MAX3223EAP+ 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 AutoShutdown™ when no valid signal is detected on receiver inputs for 30µs. The device guarantees a 120kbps data rate with worst-case loads of 3kΩ parallel 1000pF, typically supporting up to 235kbps. 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 technology reduces power consumption by disabling the onboard power supply and drivers when no valid RS-232 signal is present at the receiver inputs.
Integrated dual charge-pump circuitry generates true RS-232 voltage levels from a single low-voltage supply without requiring external ±12V sources.
Provides full-duplex communication with two independent drivers and two receivers compatible with EIA/TIA-232 standards.

Applications

Battery-powered equipment
Hand-held devices
Portable diagnostics equipment

Procurement Notes

Verify the component matches the specific Analog Devices/Maxim Integrated part number MAX3223EAP+. Confirm the RoHS-compliant status indicated by the '+' suffix and ensure the 20-pin SSOP package variant aligns with design requirements. Cross-reference datasheet specifications against supplier documentation to validate authenticity and electrical parameters before integration.

Selection Notes

Select this component for applications requiring low-power RS-232 connectivity in space-constrained designs. The 20-pin SSOP package suits surface-mount layouts. Ensure the system operates within the +3.0V to +5.5V range and requires only two channels. Verify that the 120kbps guaranteed rate meets interface speed needs, noting higher rates are typical but not guaranteed under all load conditions.

Part Context

This device belongs to the MAX3221/MAX3223/MAX3243 family of 3V-powered RS-232 transceivers. The MAX3223 specifically provides two drivers and two receivers, distinguishing it from the single-channel MAX3221 and the multi-channel MAX3243. All variants share the same core AutoShutdown functionality and charge-pump architecture.
