4051 IC CMOS Single 8-Channel Analog Multiplexer

Description

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 ±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 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
