MAX232ESE+

MAX232ESE+ Description

The MAX232ESE+ from Analog Devices Inc./Maxim Integrated is a high-performance RS-232 transceiver designed for surface-mount applications. This dual-driver/dual-receiver IC facilitates full-duplex communication at data rates up to 120 kbps, making it ideal for interfacing between TTL/CMOS logic levels and RS-232 serial ports. Operating within a 4.5V to 5.5V supply range, it integrates charge-pump voltage converters to generate the required ±7.5V RS-232 levels from a single 5V supply. Packaged in a 16-pin SOIC tube, it is RoHS3 compliant and features 500 mV receiver hysteresis for robust noise immunity.

MAX232ESE+ Features

• Dual Drivers/Receivers: Supports 2 TX and 2 RX channels for bidirectional communication.
• Integrated Charge Pump: Eliminates the need for external ±12V power supplies.
• Wide Supply Range: Operates from 4.5V to 5.5V, compatible with standard 5V systems.
• High Noise Immunity: 500 mV receiver hysteresis ensures reliable signal integrity in noisy environments.
