SP3220E DS/04 SP3220E True +3.0 to +5.0V RS-232 Transceivers
Copyright 2000 Sipex Corporation
+3.0V to +5.5V RS-232 Driver/Receiver Pair
SP3220E
DESCRIPTION
The
SP3220E
device is an RS-232 driver/receiver solution intended for portable or hand-held
applications such as notebook or palmtop computers. The
SP3220E
device has a high-
efficiency, charge-pump power supply that requires only 0.1
μ
F capacitors in 3.3V operation.
This charge pump allows the
SP3220E
device to deliver true RS-232 performance from a
single power supply ranging from +3.3V to +5.0V. The ESD tolerance of the
SP3220E
device
is over +15kV for both Human Body Model and IEC1000-4-2 Air discharge test methods.
The
SP3220E
device has a low-power shutdown mode where the driver outputs and charge
pumps are disabled. During shutdown, the supply current falls to less than 1
μ
A.
