Low-Voltage, Single-Supply Multiplexer and Switch
________________General Description
The MAX4524/MAX4525 are low-voltage, single-supply CMOS analog switches configured as a 4-channel mult i p l e x e r / d e m u l t i p l e x e r (MAX4524) and a doublep o l e / d o u b l e - t h r o w (DPDT) switch (MAX4525). Both have an inhibit input to simultaneously open all signal paths. These devices operate from a single supply of +2V to +12V and are optimized for operation with +3V or +5V supplies. On-resistance is 200 with a +5V supply and 500 with a +3V supply. Each switch can handle Railto-Rail® analog signals. The off-leakage current is only 2nA at +25°C or 20nA at +85°C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply.

Note 1: Voltages exceeding V+ or GND on any signal terminal are clamped by internal diodes. 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.
