MAX3232ECUP+G071

Overview

The MAX3232ECUP+G071 is a dual-channel RS-232 transceiver manufactured by Analog Devices/Maxim Integrated. It operates on a single 3V to 5.5V supply and supports data rates up to 250kbit/s. The device integrates two drivers and two receivers with ±15kV IEC ESD protection. It utilizes a dual charge-pump circuit requiring four external capacitors, typically 0.1μF, to generate the necessary internal voltages. The component is housed in a 16-pin TSSOP (PW) package measuring 5mm x 6.4mm. It features low standby current of 300μA typical and meets TIA/EIA-232-F standards.

Feature Summary

• Dual charge-pump architecture enables operation from a single power supply without negative voltage rails.
• Integrated ±15kV IEC electrostatic discharge protection on serial-port connection pins including ground.
• Low-power design with typical standby current of 300μA suitable for battery-powered applications.
• Pin-compatible with alternative high-speed devices such as SNx5C3232.

Applications

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

Procurement Notes
