______________________________________________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
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 0.1µF 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.
