MAX3232ESE+ Low-Power RS-232 Transceiver
The MAX3232ESE+ is a high-performance, low-power RS-232 transceiver designed for reliable serial communication in industrial, automotive, and portable applications. It operates on a 3V to 5.5V single-supply voltage, enabling compatibility with both 3.3V and 5V systems. The device integrates two drivers and two receivers, supporting full-duplex communication at data rates up to 250kbps while maintaining RS-232-compliant voltage levels. Its proprietary low-dropout transmitter output stage and dual charge pump architecture require only four external 0.1µF capacitors, minimizing PCB space and BOM costs. The MAX3232ESE+ features ±15kV IEC ESD protection on all pins, ensuring robustness in harsh environments, and operates across an extended temperature range of -40°C to +85°C (or -40°C to +125°C for automotive-grade variants).
Key Features & Technical Specifications
The MAX3232ESE+ elivers 120kbps guaranteed data rates (with typical performance up to 250kbps) and supports 3V to 5.5V operation, making it ideal for battery-powered devices. It consumes just 0.3mA (typical) in active mode and offers a 1µA shutdown mode for ultra-low power conservation. The device meets TIA/EIA-232-F and V.28 standards, ensuring compatibility with legacy RS-232 systems. Additional features include 300mV receiver hysteresis for noise immunity, 6V/µs slew rate control to reduce EMI, and pin compatibility with industry-standard MAX232, simplifying design upgrades. The 16-pin SOIC/TSSOP packages support surface-mount assembly, while the 3.9mm × 9.9mm footprint suits compact designs.
