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 0.5for the normally closed (NC)
switch, and 0.8for the normally opened switch (NO) at 2.7
V.
The switch features break-before-make switching action with
tON = 50ns and tOFF = 40ns at +3V. The digital logic inputs are
1.8V logic interface compatible with a +2.7V to +3.3V supply.
