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
