The low on-resistance (RON = 40Ω at ±5V) and low power consumption (5µW) make this part ideal for audio, video, and battery-powered applications. This switch offers low leakage currents (1nA max) and fast switching speeds (tON = 60ns and tOFF = 40ns at ±5V, max). The MAX4564 is available in 8-pin SOT23 and µMAX packages.

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.

The MAX4564 has break-before-make switching. The CMOS switch construction provides Rail-toRail ® signal handling while consuming virtually no power. Each of the two switches is independently controlled by a TTL/CMOS-level-compatible digital input. POSITIVE SUPPLY D1 V+ Applications Information MAX4564 Overvoltage Protection Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the device. Proper power-supply sequencing is recommended for all CMOS devices. Always sequence V+ on first, then V-, followed by the logic inputs NO, NC, or COM. If power-supply sequencing is not possible, add two small-signal diodes (D1, D2) in series with supply pins. Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the device’s low switch resistance and low leakage characteristics.
