SP3238 Inteligent RS-232 Driver (TSSOP-28) – SMD


20 in stock


The SP3238 device is an RS-232 transceiver solution intended for portable or hand-held
applications such as notebook and palmtop computers. The SP3238 uses an internal
high-efficiency, charge-pump power supply that requires only 0.1µF capacitors in 3.3V
operation. This charge pump and Sipex’s driver architecture allow the SP3238 device to
deliver compliant RS-232 performance from a single power supply ranging from +3.0V to
+5.0V. The SP3238 is a 5-driver/3-receiver device, ideal for laptop/notebook computer and
PDA applications. The SP3238 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.
