Customers must be aware of the suitability of this product for their application, and consider that variable factors such as Manufacturer, Product Category, Date Codes, Pictures and Descriptions may differ from available inventory.

General Description
The MAX4635/MAX4636 are fast, dual 4Ω single-
pole/double-throw (SPDT) analog switches that operate
with supply voltages from +1.8V to +5.5V. High switch-
ing 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 min-
imal impact on your power budget. The analog signal
range extends to the supply rails. The MAX4635 has
inverted logic compared to the MAX4636.

(Notes 2, 9)
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.
