4051 IC CMOS Single 8-Channel Analog Multiplexer

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 100pA (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
