These multiplexer circuits dissipate extremely low quiescent power over the full VCC -GND and VCC - VEE 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. The IW4053B is a triple 2-channel multiplexer having three separate digital control inputs, A, B, and C, and an enable input. Each control input selects one of a pair of channels which are connected in a single-pole double-throw configuration. Operating Voltage Range: 3.0 to 18 V Maximum input current of 1 A at 18 V over full packagetemperature range; 100 nA at 18 V and 25C Noise margin (over full package temperature range): 1.0 V min @ 5.0 V supply
