CD4051 Single 8-channel Multiplexer/Demultiplexer

CD4051 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC’s) constructed with N- and P-channel enhancement mode transistors. CD4051 has a Single 8-channel Multiplexer/Demultiplexer

CD4051 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.

CD4051 Features

• Wide range of digital and analog signal levels:
  • digital 3 – 15V, analog to 15Vp-p
• Low “ON” resistance: 80Ω (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 = 5Ω (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
