The MAX3232CPWR is a circuit manufactured by Texas Instruments that is specifically designed to enable logic-level serial communication between devices operating at different voltage levels. This device is capable of converting digital signals from devices operating at logic-level voltages of 3.0 V or 5.0 V to asynchronous serial communications protocols, as well as RS-232, that operate at ±15-kV ESD-protected transceivers. It also functions as an interface between the 3.0 V to 5.0 V logic and the legacy RS-232 bus. It features fast slew-rate limiting, low power inputs and outputs, and high data-transfer rates up to 250 kbits/s. The MAX3232CPWR is designed specifically for applications that require a wide operating supply voltage range and low EMI-noise emission. This device is a reliable choice for use in PDA, modem, cellphone, and notebook applications.
