... R6 10 GND 9 TERMPWR2 8 DS2105S 16–PIN SOIC (300 MIL) consumption. The DS2105, which integrates a regula- tor and nine precise switched 110 ohm termination re- sistors into a monolithic IC functionally compatible version of the DS21S07A. With relaxed output current and termination tolerances, the DS2105 is intended for high volume applications which require active termina- tion but not the high performance of the DS21S07A ...
