DESCRIPTION.
The SP207H and SP211H are multi-channel RS-232 line transceivers configured
to fit most communication needs. The "H" series is based on Sipex's SP200
Series
transceivers and has been enhanced for speed. The data rate is improved to
over 460kbps which
easily meets the 230.4kbps data rates for V.34. The SP207H and SP211H use
the same on-board
charge pump to provide ?10V voltage levels, using 0.1mF charge pump
capacitors to save
board space and reduce circuit cost. The SP207HB, SP211H and SP211HB feature
a low-power
shutdown mode, which reduces power supply drain to 1mA. A WakeUp function
keeps the
receivers active in the shutdown mode (SP207HB and SP211HB only).
