General Description
SP3282EB General Description
The SP3282EB device is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook and palmtop computers, PDAs, cell phones and their data cables and cradles.
The SP3282EB is compatible with low voltage logic down to 1.8V using a logic select pin (VL) which conditions the logic inputs and outputs to be compatible with system logic.
The SP3282EB uses 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 SP3282EB device to deliver compliant RS-232 performance from a single +3.3V to +5.5Vpower supply and additionally adhere to EIA/TIA-562 driver outputs levels down to a power supply voltage of 2.35V.
The AUTO ON-LINE® 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.
SP3282EB Maximum Ratings
These are stress ratings only and functional operation of the device at these ratings or any other above those indicated in the operation sections of the specifications below is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability and cause permanent damage to the device.
