DescriptionThe SP3222H and the 3232H 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 0.1F capacitors for 3.3V operation. The charge pump allows the SP3222H and the 3232H series to deliver true RS-232 performance from a single power supply ranging from +3.3V to +5.0V.
The SP3222H 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 1A.
The SP3222H and SP3232H are 2-driver/ 2-receiver devices ideal for portable or hand-held applications. The SP3222 H features a 1A shutdown mode that reduces power consumption and extends battery life in portable systems. Its receivers remain active in shutdown mode, allowing external devices such as modems to be monitored using only 1A supply current.
The SP3222H/3232H transceivers meet the EIA/ TIA-232 and V.28/V.24 communication protocols. They feature Sipex's proprietary on-board charge pump circuitry that generates 2 x VCC for RS-232 voltage levels from a single +3.0V to +5.5V power supply. The SP3222 H/ 3232H drivers operate at a minimum data rate of 460Kbps.
