MAX3232EEWE+T

Overview

The MAX3232EEWE+T is a low-power, true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers operating from a single 3V to 5.5V supply voltage. The device utilizes a dual charge-pump circuit requiring four external 0.1μF capacitors for operation. It supports data rates up to 250kbit/s with a maximum driver output slew rate of 30V/μs. The component operates within a temperature range of -40°C to +85°C and draws a typical supply current of 1mA. It is housed in a 16-pin SO-Wide package.

Feature Summary

• Dual charge-pump architecture enables true RS-232 performance using only four small external capacitors.
• Provides full duplex communication with two independent drivers and two receivers.
• Operates reliably across a wide supply voltage range from 3V to 5.5V.

Applications

• Industrial PCs
• Wired networking equipment
• Data center and enterprise computing systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the intended PCB layout dimensions for the 16-SOIC package. Confirm that the component meets all required environmental standards for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a low-power RS-232 interface is required for 3V or 5V logic systems. It serves as a pin-compatible alternative to legacy MAX232 devices while offering improved power efficiency. Verify that the system design accommodates the necessary external capacitor footprint for the charge pump circuitry.

Part Context

This part belongs to the MAX3232E series of RS-232 transceivers designed for portable and battery-powered applications. The 'EE' designation typically indicates an extended temperature range variant, while the '+T' suffix denotes tape-and-reel packaging for automated assembly processes.

Replacement Considerations

The SNx5C3232 is identified as a pin-compatible high-speed alternative. Verify electrical parameter alignment and package compatibility before substituting.
