High switching speeds, 1Ω on-resistance flatness, and low power consumption make these devices ideal for audio/video, communications, and battery-operated devices. Containing two independently controllable SPDT switches in 10-pin µMAX and 10-pin 3mm x 3mm thin QFN packages, the MAX4635/MAX4636 use little board space, and have low power consumption ensuring minimal impact on your power budget. The analog signal range extends to the supply rails. The MAX4635 has inverted logic compared to the MAX4636.

Limit forward-diode current to maximum current rating. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

This allows interfacing to 5V logic signals while operating with a +3.3V supply voltage without external level translation. The MAX4635/MAX4636 are low-on-resistance (RON), low-voltage, dual SPDT analog switches that operate from a +1.8V to +5.5V supply. The MAX4635/MAX4636 feature very fast switching speed (tON = 14ns max, tOFF = 6ns max) and guaranteed break-before-make switching. The low maximum RON allows high continuous currents to be switched in a variety of applications. Analog Signal Levels Analog signals ranging 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 may be used as either inputs or outputs. Applications Information 10nF Power-Supply Sequencing and Overvoltage Protection V+ V+ COM_ MAX4635 MAX4636 VINL OR VINH IN_ CAPACITANCE METER NC_ OR NO_ f = 1MHz 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 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 less than 30mA, add a small-signal diode (D1) as shown in Figure 5. 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). GND Figure 3.

Overvoltage Protection Using Two External Blocking Diodes On-resistance increases slightly at low supply voltages. Maximum supply voltage (V+) must not exceed +6V. Adding protection diode D2 causes the logic threshold to be shifted relative to GND. Protection diodes D1 and D2 also protect against some overvoltage situations. With Figure 5’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 MAX4635/MAX4636 Chip Information POSITIVE SUPPLY Package Information (The package drawing(s) in this data sheet may not reflect the most current specifications.
