The MAX323/MAX324/MAX325 a re p re c is ion, d ua l,
SPST analog switches. They are single-supply devices
designed to operate from +2.7V to +16V. The MAX323
has two normally open (NO) switches, and the MAX324
has two normally closed (NC) switches. The MAX325
has one NO and one NC switch. Low power consump-
tion (5µW) makes these parts ideal for battery-powered
equipment. These switches offer low leakage currents
