1. Description

The CD4051BM analog multiplexers and demultiplexers 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.

2. Features

   1. Wide Range of Digital and Analog Signal Levels

       – Digital: 3 V to 20 V

       – Analog: ≤ 20 VP-P

   2. Low ON Resistance, 125 Ω (Typical) Over 15 VP-P Signal Input Range for VDD – VEE = 18 V

   3. High OFF Resistance, Channel Leakage of ±100 pA (Typical) at VDD – VEE = 18 V

   4. 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

   5. Binary Address Decoding on Chip

   6. 5 V, 10 V, and 15 V Parametric Ratings

   7. 100% Tested for Quiescent Current at 20 V

   8. Maximum Input Current of 1 µA at 18 V Over Full Package Temperature Range, 100 nA at 18 V and 25°C

   9. Break-Before-Make Switching Eliminates Channel Overlap
