Now Available in Lead Free Packaging
The SP3238E device is an RS-232 transceiver solution intended for portable or hand-held applications
such as notebook and palmtop computers. The SP3238E uses an internal high-efficiency, charge-pump
power supply that requires only 0.1µF capacitors in 3.3V operation. This charge pump and Exar's driver
architecture allow the SP3238E device to deliver compliant RS-232 performance from a single power
supply ranging from +3.0V to +5.5V. The SP3238E is a 5-driver / 3-receiver device that is ideal for laptop
/ notebook computer and PDA applications. The SP3238E includes one complementary receiver that
remains alert to monitor an external device's Ring Indicate signal while the device is shutdown.
The
AUTO ON-LINE
®
feature allows the device to automatically "wake-up" during a shutdown state
when an RS-232 cable is connected and a connected peripheral is turned on. Otherwise, the device
automatically shuts itself down drawing less than 1µA.
