MAX232CSE+ is a low-power, dual channel, wide supply-voltage range, +5 V powered, charging pump, RS-232 driver / receiver. It is designed to operate over a wide range of supply voltage, from 1.4V to 5.5V, and offers low power consumption for battery operated applications. Features of the MAX232CSE+ include improved ESD protection, low input capacitance, and a high output voltage swing (8.2V). The MAX232CSE+ provides one or two drivers and two receivers for RS-232/V.24 communications, and is suitable for data rates up to 120kbps. The driver/receiver outputs feature Schmitt-trigger inputs, which allow logic-level noise immunity. The MAX232CSE+ also features an active-low shutdown pin that can reduce the supply current to 3µA. Additionally, the MAX232CSE+ provides both power-on reset and charge-pump reset outputs, which can be used to reset peripheral devices in low-power applications.
