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 0.1µF 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 1µA. A WakeUp function keeps the receivers active  
in the shutdown mode (SP207HB and SP211HB only).
