MAX3232ESE+T

The MAX3232ESE+T is a true RS-232 transceiver manufactured by Maxim Integrated. It is designed for reliable RS-232 communication using a proprietary low-dropout transmitter output stage, enabling operation from a wide single supply voltage range of +3.0V to +5.5V. This device requires only four small external charge-pump capacitors, simplifying design and saving board space.

The MAX3232ESE+T is guaranteed to operate at data rates of 120kbps while maintaining RS-232 output levels. It features 2 receivers and 2 drivers, making it pin and functionally compatible with industry-standard MAX232 devices. The transceiver is available in space-saving TSSOP and SSOP packages, suitable for various applications including battery-powered equipment, hand-held devices, and peripherals.

Key features include integrated charge pump circuitry that eliminates the need for a bipolar ±12V supply and power-saving capabilities, with a supply current of just 1µA in shutdown mode while the receiver is active. The operating temperature range is typically -40°C to +85°C or 0°C to 70°C, depending on the specific variant.

This transceiver is well-suited for applications requiring robust serial communication interfaces where space and power efficiency are critical. Its compatibility with standard RS-232 levels and single-supply operation makes it a versatile choice for many datacom equipment designs.
