Low-Voltage, Quad, SPST CMOS Analog Switches
General Description
The MAX4610/MAX4611/MAX4612 quad, low-voltage, single-pole/single-throw (SPST) analog switches are pin-compatible with the industry-standard 74HC4066 analog switch. On-resistance (100 max) is matched between switches to 4 max and is flat (4 max) over the specified signal range. Each switch handles V+ to GND analog signal levels. Maximum off-leakage current is only 1nA at TA = +25C and 2nA at TA = +85C. The MAX4610 has four normally open (NO) switches, and the MAX4611 has four normally closed (NC) switches. The MAX4612 has two NO switches and two NC switches. These CMOS switches operate from a single +2V to +12V supply. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply.

Note 1: Signals on NO_, NC_, COM_, or IN_ exceeding V+ or GND 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.

Applications Information
Power-Supply Sequencing and Overvoltage Protection
Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings may cause permanent damage to the devices. Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals or logic inputs, especially if the analog or logic signals are not current limited. If this sequencing is not possible, and if the analog or logic inputs are not current limited to 20mA, add a small-signal diode (D1) as shown in Figure 1. If the analog signal can dip below GND, add D2. Adding protection diodes reduces the analog signal range to a diode drop (about 0.7V) below V+ (for D1), and to a diode drop above ground (for D2). Leakage is unaffected by adding the diodes. On-resistance increases by a small amount at low supply voltages. Maximum supply voltage (V+) must not exceed 13V. Adding protection diodes causes the logic thresholds to be shifted relative to the power-supply rails. This can be significant when low supply voltages (+5V or less) are used. With a +5V supply, TTL compatibility is not guaranteed when protection diodes are added. Driving IN1 and IN2 all the way to the supply rails (i.e., to a

diode drop higher than the V+ pin, or to a diode drop lower than the GND pin) is always acceptable. Protection diodes D1 and D2 also protect against some overvoltage situations. With Figure 1'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 will result.

Operating Considerations for High-Voltage Supply
The MAX4610/MAX4611/MAX4612 are pin-compatible with the industry-standard 74HC4066 and the MAX4066, and are optimized for +5V single-supply operation. The MAX4610 family is capable of +12V single-supply operation with some precautions. The absolute maximum rating for V+ is +13.2V (referenced to GND). When operating near this region, bypass V+ with a minimum 0.1F capacitor to ground as close to the IC as possible. Caution: The absolute maximum V+ to V- differential voltage is 13.0V. Typical 6V or 12V supplies with 10% tolerances can be as high as 13.2V. This voltage can damage the MAX4610/MAX4611/MAX4612. Even 5% tolerance supplies may have overshoot or noise spikes that exceed 13.0V.
