Copyright 2003 Sipex Corporation
High Speed +3.0V to +5.5V RS-232 Driver/Receiver Pair
SP3220B/U
DESCRIPTION
The
SP3220B/U
device is an RS-232 driver/receiver solution intended for portable or hand-held
applications such as notebook or palmtop computers. The
SP3220B/U
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
SP3220B/U
device to deliver true RS-232 performance from a single
power supply ranging from +3.3V to +5.0V.
The
SP3220B/U
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.
