7. Levels Analog signals that range over the entire supply voltage V to GND can be passed with very little change in on resistance see Typical Operating Characteristics The switches are bidirectional so the NO NC and COM pins can be used as either inputs or outputs Power Supply Sequencing and Overvoltage Protection Caution Do not exceed the absolute maximum rat ings stresses beyond the listed ratings may cause permanent damage to the devices Proper power supply sequencing is recommended for all CMOS devices Always apply V before applying analog signals especially if the analog signal is not current limited If this sequencing is not possible and if the analog inputs are not current limited to lt 20mA add a small signal diode D1 as shown in Figure 1 If the analog signal can dip below GND add D2 Adding protection diodes reduces the analog range to a diode drop about 0 7V below V for D1 and a diode drop above ground for D2 On resistance increases by a small amount at low supply voltages Maximum supply voltage V must not exceed 6V Adding protection diode D2 causes the logic thresh olds to be shifted relative to GND TTL compatibility is not guaranteed when protection diode D2 is added Protection diodes D1 and D2 also protect against some overvoltage situations With Figure 1 s circuit if the sup ply voltage is below the absolute maximum rating and if a fault voltage up to the absolute maximum ratin
