MAX3232ECAE

Overview

The MAX3232ECAE is a dual RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 3V to 5.5V supply and includes two drivers and two receivers. The device utilizes a dual charge-pump circuit requiring four external capacitors to generate the necessary RS-232 voltage levels. It supports data rates up to 250kbit/s with a maximum driver output slew rate of 30V/μs. The component features ±15kV IEC ESD protection on serial-port connection pins, including ground. It is housed in a 16-pin SSOP package.

Feature Summary

• Dual channel RS-232 transceiver with integrated charge pump
• Single power supply operation from 3V to 5.5V
• Integrated ±15kV IEC ESD protection on all serial port pins

Applications

• Industrial PCs
• Wired networking equipment
• Data center and enterprise computing systems
• Battery-powered portable devices

Procurement Notes

Verify the specific suffix 'CAE' against official manufacturer documentation to confirm exact package dimensions and temperature range specifications. Ensure compatibility with the required operating environment before procurement. Cross-reference ordering information directly with Analog Devices or Maxim Integrated authorized distributors to validate current production status and availability.

Selection Notes

Select this component for applications requiring full-duplex RS-232 communication between TTL/CMOS logic and standard serial ports. It is suitable for designs constrained by space due to its compact SSOP packaging. Verify that the system power supply remains within the 3V to 5.5V range. Confirm that the required data rate does not exceed 250kbit/s for optimal performance under specified load conditions.

Part Context

This part belongs to the MAX3232 family of low-power RS-232 transceivers. It shares functional similarities with other members like the MAX3232E but differs in specific package and thermal characteristics. The CAE suffix typically denotes a specific commercial grade variant in the SSOP package format. It serves as a bridge between microcontrollers and legacy serial interfaces.

Replacement Considerations

The SNx5C3232 series is identified as a pin-compatible alternative offering higher speed capabilities. Verify electrical parameter alignment and package footprint compatibility before substitution. Consult official cross-reference guides for detailed pin-to-pin mapping and operational differences.
