General Description
The MAX4664/MAX4665/MAX4666 quad analog switch­es feature 5Ω max on-resistance. On-resistance is matched between switches to 0.5Ω max and is flat (0.5Ω max) over the specified signal range. Each switch can handle Rail-to-Rail®analog signals. The off-leakage cur­rent is only 5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the pre­ferred solution over mechanical relays in automatic test equipment or in applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays.
The MAX4664 has four normally closed (NC) switches, the MAX4665 has four normally open (NO) switches, and the MAX4666 has two NC and two NO switches that guarantee break-before-make switching times.
These switches operate from a single +4.5V to +36V supply or from dual ±4.5V to ±20V supplies. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±15V sup­plies or a single +12V supply.

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
Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maxi­mum ratings, because stresses beyond the listed rat­ings can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with supply pins (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices’ low switch resistance and low leak­age characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed 44V. These protection diodes are not recom­mended when using a single supply.
Off-Isolation at High Frequencies
In 50Ω systems, the high-frequency on-response of these parts extends from DC to above 100MHz, with a typical loss of -2dB. When the switch is turned off, how­ever, it behaves like a capacitor, and off-isolation decreases with increasing frequency. (Above 300MHz,
the switch actually passes more signal turned off than turned on.) This effect is more pronounced with higher source and load impedances.

Figure 2. Switching-Time Test Circuit
Above 5MHz, circuit board layout becomes critical, and it becomes difficult to characterize the response of the switch independent of the circuit. The graphs shown in the
Typical Operating Characteristics
were
taken using a 50Ω source and load connected with BNC connectors to a circuit board deemed “average,”
that is, designed with isolation in mind, but not using stripline or other special RF circuit techniques. For criti­cal applications above 5MHz, use the MAX440, MAX441, and MAX442, which are fully characterized up to 160MHz.
