9-79; Rev ; /3 Fast, Low-Voltage, Dual 4 SPDT General Description The are fast, dual 4 singlepole/double-throw (SPDT) analog switches that operate with supply voltages from +.8V to +.V. High switching speeds, on-resistance flatness, and low power coumption make these devices ideal for audio/video, communicatio, and battery-operated devices. Containing two independently controllable SPDT switches in -pin µmax and -pin 3mm x 3mm thin QFN packages, the use little board space, and have low power coumption euring minimal impact on your power budget. The analog signal range extends to the supply rails. The MAX463 has inverted logic compared to the.

Detailed Description The are low-on-resistance (R ), low-voltage, dual SPDT analog switches that operate from a +.8V to +.V supply. The feature very fast switching speed (t = 4 max, t = 6 max) and guaranteed break-before-make switching. The low maximum R allows high continuous currents to be switched in a variety of applicatio. Applicatio Information CAPACITANCE METER f = MHz nf NC_ OR NO_ Figure 3. Channel Off/On-Capacitance MAX463 IN_ L OR H Logic Inputs The logic inputs (IN, IN) can be driven up to +.V, regardless of the voltage on. This allows interfacing to V logic signals while operating with a +3.3V supply voltage without external level tralation. Analog Signal Levels Analog signals ranging over the entire supply voltage ( to ) can be passed with very little change in on-resistance (see Typical Operating Characteristics). The switches are bidirectional, so the NO_, NC_, and pi may be used as either inputs or outputs. Power-Supply Sequencing and Overvoltage Protection Caution: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the device. Proper power-supply sequencing is recommended for all CMOS devices. Always apply 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 less than 3mA, add a small-signal diode (D) as shown in Figure. If the analog signal can dip below, add D. Adding protection diodes reduces the analog range to a diode drop (about.7v) below (for D), and a diode drop above ground (for D).

Maximum supply voltage () must not exceed +6V. Adding protection diode D causes the logic threshold to be shifted relative to. Protection diodes D and D also protect agait some overvoltage situatio. With Figure s circuit, if the supply voltage is below the absolute maximum rating, and if a fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage results. 9
