The "H" series is based on Sipex's SP3223E/3243E series and has been enhanced for high speed.
The data rate is improved to 460Kbps, easily meeting the demands of high speed RS-232 applications.
The SP3223EH and 3243EH use an internal high-efficiency, charge-pump power supply that requires only 0.
1µF capacitors in 3.
3V operation.
This charge pump and Sipex's driver architecture allow the SP3223EH/3243EH series to deliver compliant RS-232 performance from a single power supply ranging from +3.
3V to +5.
0V.
The SP3223EH is a 2-driver/2-receiver device, and the SP3243EH is a 3-driver/5-receiver device, ideal for laptop/notebook computer and PDA applications.
The SP3243EH includes one complementary receiver that remains alert to monitor an external device's Ring Indicate signal while the device is shutdown.
The Auto-Online feature allows the device to automatically "wake-up" during a shutdown state when an RS-232 cable is connected and a connected peripheral is turned on.
Otherwise, the device automatically shuts itself down drawing less than 1µA.
