1 TECHNICAL DATA IW0B Analog Muliplexer Demuliplexer HighPerformance SiliconGae CMOS The IW0B analog muliplexer/demuliplexer is digially conrolled analog swiches having low ON impedance and very low OFF leakage curren. Conrol of analog signals up o peakopeak can be achieved by digial signal ampliudes of. o (if CC =, a CC EE of up o can be conrolled; for CC EE level differences above a CC of a leas. is required). These muliplexer circuis dissipae exremely low quiescen power over he full CC and CC EE supplyvolage ranges, independen of he logic sae of he conrol signals. When a logic is presen a he ENABLE inpu erminal all channels are off. The IW0B is a single 8channel muliplexer having hree binary conrol inpus, A, B and C, and an ENABLE inpu. The hree binary signals selec of 8 channels o be urned on, and connec one of he 8 inpus o he oupu.
