MAX3222EEUP+T

Overview

The MAX3222EEUP+T is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-pin TSSOP package. It operates on a single +3.0V to +5.5V supply and features two drivers and two receivers for full-duplex communication. The device guarantees data rates up to 250kbps with typical propagation delays of 0.3µs. It incorporates an internal dual charge pump requiring four 0.1µF capacitors. Supply current is typically 1mA, dropping to 1µA in shutdown mode. ESD protection reaches ±15kV via the Human Body Model. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Integrated dual charge pump enables operation from a single low-voltage supply without external voltage inversion circuits.
• Enhanced electrostatic discharge protection safeguards transmitter outputs and receiver inputs against high-voltage static events.
• Dedicated shutdown control significantly reduces power consumption while maintaining receiver activity for external device monitoring.

Applications

• Battery-powered portable equipment
• Cell phone and smartphone data cables
• Notebook and subnotebook computers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging specifications prior to acquisition. Ensure the specific ordering suffix matches the required thermal and mechanical parameters for the target application environment.

Selection Notes

Select this component when designing systems requiring compatibility with industry-standard MAX232 interfaces but operating at lower voltages. The 20-pin TSSOP package suits space-constrained designs. Verify that the required data rate does not exceed 250kbps and that the system can accommodate the necessary external charge-pump capacitors.

Part Context

This part belongs to the MAX3222E family of RS-232 transceivers designed for low-power applications. It serves as a functional replacement for legacy MAX232 devices in modern low-voltage environments. The EE designation indicates an extended industrial temperature range suitable for demanding operational conditions.

Replacement Considerations

The MAX3222EEUP/V+T is an automotive-qualified alternative within the same series. Direct pin-compatible replacements include other variants from the MAX3222E family, provided the package type and temperature range requirements are met.
