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.
