SP3282EB
Intelligent +2.35V to +5.5V RS-232 Transceivers
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
0.1
μ
F 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 1
μ
A.
