MAX4649EKA+T

The MAX4649 is a high-voltage, single-pole/doublethrow (SPDT) analog switch that operates from dual ±4.5V to ±20V supplies or from a single +9V to +36V supply. The MAX4649 has one normally closed (NC) switch and one normally open (NO) switch. CMOS switch construction allows bidirectional processing of rail-to-rail analog signals. The MAX4649 has break-before-make switching. The transition time for switching from one input to the other is typically 90ns. The off-leakage is typically less than 10pA, and on-leakage is typically less than 20pA.
