DESCRIPTION
The
SP3222EH
and the
3232EH
are 2 driver/2 receiver RS-232 transceiver solutions
intended for portable or hand-held applications such as notebook or palmtop computers.
Their data transmission rate of 460Kbps meeting the demands of high speed RS-232
applications. Both ICS have a high-efficiency, charge-pump power supply that requires only
0.1µF capacitors for 3.3V operation. The charge pump allows the
SP3222EH
and the
3232EH
series to deliver true RS-232 performance from a single power supply ranging from +3.3V
to +5.0V. The ESD tolerance of the
SP3222EH/3232EH
devices exceeds
+15kV
for both
Human Body Model and IEC1000-4-2 Air discharge test methods.
The
SP3222EH
device has a low-power shutdown mode where the devices' driver outputs
and charge pumps are disabled. During shutdown, the supply current is less than 1µA.
