______________________________________________Test Circuits/Timing Diagrams

Protection diodes D1 and D2 also protect against some

overvoltage situations. With Figure 1’s circuit, if the sup-

ply 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 sin-

gle-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 0.1µF 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 volt-

age can damage the MAX4610/MAX4611/MAX4612.

Even ±5% tolerance supplies may have overshoot or

noise spikes that exceed 13.0V.
