MAX232AEUE+T

Overview

The MAX232AEUE+T is a dual transmitter and receiver RS-232 transceiver from the MAX220–MAX249 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply using internal charge-pump circuitry to generate ±10V levels. The device supports data rates up to 200 kbps with full duplex communication. It features an industrial temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP package. Electrical specifications include a typical VCC supply current of 10 mA under load and propagation delays of 3.5 µs for both transmit and receive paths.

Feature Summary

• Integrates dual charge-pump voltage converters to eliminate the need for external bipolar power supplies
• Provides EIA/TIA-232E compliant signal levels directly from a single +5V source
• Includes shutdown mode functionality to minimize power consumption during idle periods

Applications

• Interface translation between TTL/CMOS logic and RS-232 serial ports
• Multidrop RS-232 network connections
• Portable diagnostic equipment requiring low power operation

Procurement Notes

Verify the specific suffix 'UE' corresponds to the TSSOP-16 package variant when sourcing. Confirm that the '+T' designation indicates tape-and-reel packaging if required for automated assembly processes. Ensure the component meets RoHS compliance standards as indicated by the manufacturer's documentation.

Selection Notes

Select this component for designs requiring reduced board space through integrated capacitors or standard external capacitor configurations. Compare against the MAX232CWE+T for commercial temperature variants or the MAX232EESE+ for higher ESD protection ratings. Evaluate the 200 kbps data rate limit against system requirements before finalizing the selection.

Part Context

This part belongs to the MAX220–MAX249 family of +5V-powered multichannel RS-232 drivers and receivers. The family offers various pin counts and feature sets, ranging from basic dual-channel devices to complex multi-channel transceivers with enable controls. The MAX232A variant specifically denotes improved electrical characteristics over the standard MAX232.
