KK4051B

The KK4051B 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 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 EE-GND and  V _CC - V   _CC 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 KK4051B 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.
