CD4051 Multiplexer/Demultiplexer
RWF 1,000
CD4051 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.
Product Description
1.Wide Range of Digital and Analog Signal Levels
- Digital: 3 V to 20 V
- Analog: ?20 VP-P
2.Low ON Resistance,125 ? (Typical) Over 15 VP-PSignal Input Range for VDD � VEE = 18 V
3.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
4.Binary Address Decoding on Chip
5-5 V, 10 V, and 15 V Parametric Ratings
6-100% Tested for Quiescent Current at 20 V
7.Maximum Input Current of 1 �A at 18 V Over Full Package Temperature Range, 100 nA at 18 V and 25�C
8.Break-Before-Make Switching Eliminates Channel Overlap
