SL4051B

SL4051B Analog Multiplexer Demultiplexer High-Performance Silicon-Gate CMOS The SL4051B analog multiplexer/demultiplexer 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 VCC - GND = 3V, a VCC - VEE of up to 13 V can be controlled; for VCC - VEE level differences above 13V a VCC - GND of at least 4.5V is required). 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 SL4051B is a single 8-channel multiplexer having three binary control inputs, A,B and C, and an ENABLE input. The three binary signals select 1 of 8 channels to be turned on, and connect one of the 8 inputs to the output. Operating Voltage Range: 3.0 to 18 V Maximum input current of 1 µA at 18 V over full packagetemperature range; 100 nA at 18 V and 25°C Noise margin (over full package temperature range): 1.0 V min @ 5.0 V supply 2.0 V min @ 10.0 V supply 2.5 V min @ 15.0 V supply ORDERING INFORMATION SL4051BN Plastic SL4051BD SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM Single-Pole, 8-Position Plus Common Off FUNCTION TABLE Control Inputs Enable C L L L L L PIN 16 =VCC PIN 7 = VEE PIN 8 = GND L L L H L L L L H H...
