9 // Detailed Description The // are low.9ω max (at = 3V) on-resistance, low-voltage quad analog switches that operate from a +1.V to +3.V single supply. CMOS construction allows switching analog signals that are within the supply voltage range ( to ). When powered from a +3V supply, the.9ω (max) R allows high continuous currents to be switched in a variety of applications. Applications Information Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence on first, followed by NO_, NC_, or COM_. If power-supply sequencing is not possible, add two small-signal diodes (D1, D2) in series with the supply pins for overvoltage protection (Figure ). Adding these diodes reduces the analog signal by one diode drop below and one diode drop above, but does not affect the low switch resistance and low leakage characteristics of the device. Device operation is unchanged, and the difference between and should not exceed 4V. V g COM POSITIVE SUPPLY Power-supply bypassing is needed to improve noise margin and to prevent switching noise propagation from the supply to other components. A.1µF capacitor, connected from to, is adequate for most applications. Logic Inputs The // logic inputs can be driven up to +3.V regardless of the supply voltage. For example, with a +1.8V supply, may be driven low to and high to +3.V. Driving rail-to-rail minimizes power consumption. Analog Signal Levels Analog signals that range over the entire supply voltage ( to ) can be passed with very little change in onresistance (see the Typical Operating Characteristics). The switches are bidirectional, so the NO_, NC_, and COM_ pins can be used as either inputs or outputs. Layout High-speed switches require proper layout and design procedures for optimum performance. Reduce stray inductance and capacitance by keeping traces short and wide. Ensure that bypass capacitors are as close to the device as possible. Use large ground planes where possible.
