DG444CY+

Analog Switches, Multiplexers, Demultiplexers Overview

The DG444CY+ is a quad, single-pole/single-throw (SPST) analog switch fabricated with a silicon-gate process. It features an on-resistance of 85 ohms maximum and operates from a single +10V to +30V supply or bipolar ±4.5V to ±20V supplies. The device guarantees low charge injection of 10pC maximum and low power consumption of 35µW maximum. Switching times are less than 250ns for turn-on and less than 70ns for turn-off. It provides electrostatic discharge tolerance of 2000V minimum per Method 3015.7.
