DESCRIPTION

The SP3244E/3245E is a 3-driver/5-receiver device ideal for mobile phone, consumer and PDA applications. These devices use an internal high-efficiency, charge-pump power supply that requires only 0.1µF capacitors for 3.3V single-supply operation. This charge pump and Sipex’s driver architecture allow the SP3244E/3245E to deliver compliant RS-232 performance from a power supply ranging from +3.0V to +5.5V. At voltages between +2.7V and +3.0V the driver outputs are compliant with RS-562 and can interface to RS-232 in portable applications.
