technical data IW4052B analog multiplexer demultiplexer high-performance silicon-gate cmos n suffix plastic d suffix soic 1 16 1 16 ordering information the IW4052B analog multiplexer/demultip lexer is digitally controlled analog switches having low on impedance and very low off leakage current. control of analog signals up to 20v peak-to-peak can be achieved by digital signal amplitudes of 4.5 to 20v (if v cc - gnd = 3v, a v cc - v ee of up to 13 v can be controlled; for v cc - v ee level differences above 13v a v cc - gnd of at least 4.5v is required). these multiplexer circuits dissipate extremely low quiescent power over the full v cc -gnd and v cc - v ee supply-voltage ranges, independent of the logic state of the control signals. when a logic ?1?is present at the enable input terminal all channels are off. IW4052Bn plastic dip IW4052Bd soic the iw4052 is a differential 4-channel multiplexer having two binary control inputs. a and b, and an enable input. the two binary input signals select 1 of 4 pairs of channels to turned on and connect the analog inputs to the outputs. t a = -55 to 125 c for all packages ? operating voltage range: 3.0 to 18 v ? maximum input current of 1 a at 18 v over full package-temperature ? range; 100 na at 18 v and 25 c ? noise margin (over full p ackage temperature range): pin assignment 1.0 v min @ 5.0 v supply 2.0 v min @ 10.0 v supply 2.5 v min @ 15.0 v supply logic diagram double-pole, 4-position plus common off function table control inputs on enable select channels b a l l l y0 x0 l l h y1 x1 l h l y2 x2 l h h y3 x3 rev. 00 h x x none pin 16 =v cc pin 7 = v ee pin 8 = gnd h = high level l = low level x = don?t care
