General Description
SP3249E General Description
The SP3249E device is an RS-232 transceiver solution intended for portable or hand-held applications such as notebook and palmtop computers. The SP3249E uses an internal high-efficiency, charge-pump power supply that requires only 0.1F capacitors in 3.3V operation. This charge pump and Sipex's driver architecture allow the SP3249E device to deliver compliant RS-232 performance from a single power supply ranging from +3.0V to +5.0V. The SP3249E is a 5-driver/3-receiver device, ideal for laptop/notebook computer and PDA applications.
SP3249E 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.
