MAX3232EEUP+TG1Z

Overview

The MAX3232EEUP+TG1Z is a dual driver and receiver RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single 3V to 5.5V supply and supports data rates up to 250kbps with a maximum slew rate of 30V/μs. The device integrates a dual charge pump circuit requiring four external capacitors, typically 0.1μF, to generate the necessary voltage levels for RS-232 communication. It features ±15kV IEC ESD protection on all serial port connection pins, including ground. The component is housed in a 16-pin TSSOP (PW) package with dimensions of 5mm x 6.4mm.

Feature Summary

• Integrates two line drivers and two line receivers for full-duplex asynchronous communication
• Includes a dual charge-pump circuit enabling operation from a single power supply without negative voltages
• Provides enhanced electrostatic discharge protection rated at ±15kV IEC standard across all interface pins

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel specifications. Confirm that the component meets the required environmental standards and operating temperature ranges for the intended application environment before finalizing procurement.

Selection Notes

Select this component when a dual-channel RS-232 interface is required within a 3V to 5.5V system. Ensure the design accommodates four external capacitors for the internal charge pump. Verify that the 250kbps data rate meets the system requirements and that the 16-pin TSSOP footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the MAX3232 family of true RS-232 transceivers designed for low-power applications. It serves as an electrical interface between asynchronous communication controllers and serial-port connectors. The device is pin-compatible with other industry-standard RS-232 transceivers, facilitating direct upgrades or replacements in existing designs.

Replacement Considerations

The SNx5C3232 series offers pin-compatible alternatives with higher data rates up to 1Mbit/s. Verify compatibility regarding supply voltage ranges and external capacitor requirements when considering these substitutes.
