CD4051 – single 8-channel analog multiplexer & demultiplexer with logic-level conversion

CD4051 – single 8-channel analog multiplexer & demultiplexer with logic-level conversion 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  (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  (Typical) for VDD VEE = 15 V Very Low Quiescent Power Dissipation Under All Digital-Control Input and Supply Conditions, 0.2 W (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 A at 18 V Over Full Package Temperature Range, 100 nA at 18 V and 25C
• Break-Before-Make Switching Eliminates Channel Overlap
