The CD4051B analog multiplexers are digitally-controlled analog switches having low ON impedance and very low OFF leakage current. These 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.

Features:

• Wide range of digital and analog signal levels
  • Digital: 3 V to 20 V
  • Analog: ≤ 20 VP-P
• Low ON resistance, 125 Ω (typical) over 15 VP-P signal input range for VDD – VEE = 18 V
• High OFF resistance, channel leakage of ±100 pA (typical) at VDD – VEE = 18 V
• Logic-level conversion for digital addressing signals of 3 V to 20 V (VDD – VSS = 3 V to 20 V) to switch analog signals to 20 VP-P (VDD – VEE = 20 V) Matched switch characteristics, rON = 5 Ω (typical) for VDD – VEE = 15 V Very low quiescent power dissipation under all digital-control input and supply conditions, 0.2 µW (typical) at VDD – VSS = VDD – VEE = 10 V
• Binary address decoding on chip
• 5 V, 10 V, and 15 V parametric ratings
• 100% tested for quiescent current at 20 V
• Maximum input current of 1 µA at 18 V over full package temperature range, 100 nA at 18 V and 25°C
• Break-before-make switching eliminates channel overlap
