The MAX3232CPE has a proprietary low-dropout transmitter stage enabling true RS232 performance from 3V to 5.5 Vdc supplies. The internal power supply consists of a regulated dual charge pump that produces output voltages of 5.5V & -5.5V from an input voltage range of 3V to 5.5V. Requiring only four 0.1micro F external capacitors for use with the charge pump circuitry the device is guaranteed to run at data rates of 120kps while maintaining RS232 output levels. The MAX3232CPE has two receivers & two drivers & is ideal for 3.3V systems mixed 3.3V5V systems or 5V systems that require true RS232 performance. The device consumes only 250micro A has a 4 Vmicros slew rate & is pin & functionally compatible with the industry standard MAX232. Applications include computers notebooks palmtops battery powered equipment h&-held equipment & peripherals. Supplied in an 18-pin DIL package.
