SW4684 Ultra-Low Resistance Dual SPDT Analog Switch .. November 2008 SW4684 Ultra-Low Resistance Dual SPDT Analog Switch General Description The SW4684 is an advanced CMOS analog switch that operates from a single +1.8V to +5.5V supply. The device is a dual independent single pole double throw (SPDT) switch featuring ultra-low RON of 0.5Ω for the normally closed (NC) switch, and 0.8Ω for the normally opened switch (NO) at 2.7 V. The switch Features break-before-make switching action with t ON = 50ns and t OFF = 40ns at +3V. The digital logic inputs are 1.8V logic interface patible with a +2.7V to +3.3V supply.
