Analog Multiplexer Single 8:1 16-Pin SOIC N T/R

The CD4051BC analog multiplexers/demultiplexers are digitally controlled analog switches having low “ON” impedance and very low “OFF” leakage currents. Control of analog signals up to 15Vp-p can be achieved by digital signal amplitudes of 3-15V. For example, if VDD = 5V, VSS = 0V and VEE = -5V, analog signals from -5V to +5V can be controlled by digital inputs of 0-5V. The multiplexer circuits dissipate extremely low quiescent power over the full VDD-VSS and VDD-VEE supply voltage ranges, independent of the logic state of the control signals. When a logical “1” is present at the inhibit input terminal all channels are “OFF”. CD4051BC is a single 8-channel multiplexer having three binary control inputs. A, B, and C, and an inhibit input. The three binary signals select 1 of 8 channels to be turned “ON” and connect the input to the output.

• Single 8-Channel
• Wide range of digital and analog signal levels: digital 3 – 15V, analog to 15Vp-p
• Low “ON” resistance: 80? (typ.) over entire 15Vp-p signal-input range for VDD - VEE = 15V
• High “OFF” resistance: channel leakage of ±10 pA (typ.) at VDD - VEE = 10V
• Logic level conversion for digital addressing signals of 3 – 15V (VDD - VSS = 3 – 15V) to switch analog signals to 15 Vp-p (VDD - VEE = 15V)
• Matched switch characteristics: ?RON = 5? (typ.) for VDD - VEE = 15V
• Very low quiescent power dissipation under all digital-control input and supply conditions:
  • 1 µ W (typ.) at VDD - VSS = VDD - VEE = 10V
• Binary address decoding on chip
