CMOS construction allows switching analog signals that are within the supply voltage range (GND to V+). When powered from a +3V supply, the 0.9 (max) RON 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 V+ 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 5). Adding these diodes reduces the analog signal by one diode drop below V+ and one diode drop above GND, but does not affect the low switch resistance and low leakage characteristics of the device. Device operation is unchanged, and the difference between V+ and GND should not exceed 4V. Power-supply bypassing is needed to improve noise margin and to prevent switching noise propagation from the V+ supply to other components. A 0.1F capacitor, connected from V+ to GND, is adequate for most applications. Logic Inputs The MAX4751/MAX4752/MAX4753 logic inputs can be driven up to +3.6V regardless of the supply voltage. For example, with a +1.8V supply, IN_ may be driven low to GND and high to +3.6V. Driving IN_ rail-to-rail minimizes power consumption. POSITIVE SUPPLY D1 MAX4751 MAX4752 MAX4753 V+ NO COM Vg GND D2 Figure 5. Overvoltage Protection Using Two External Blocking Diodes resistance (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.
