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 Exar’s driver archi-
tecture 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.
The Auto On-Line Plus feature allows the device to automatically enter a low power shutdown
mode if all receiver and driver inputs have been idle for 30 seconds. The device will “wake-up” from
this automatic shutdown state upon detecting activity. This power saving feature functions without
system intervention or modifications to software or drivers.
SP3244E supports serial data rates of 250kbps minimum under full load and while maintaining
slew rates of less than 30V/μs. SP3245E is capable of high speed communication of up to 1Mbps.
