MAX4636 Maxim, MAX4636 Datasheet - Page 9

• Manufacturer Part Number: MAX4636
• Description: The MAX4635/MAX4636 are fast, dual 4Ω single-pole/double-throw (SPDT) analog switches that operate with supply voltages from +1
• Manufacturer: Maxim

Figure 5. Overvoltage Protection Using Two External Blocking
Diodes
On-resistance increases slightly at low supply voltages.
Maximum supply voltage (V+) must not exceed +6V.
Adding protection diode D2 causes the logic threshold
to be shifted relative to GND. Protection diodes D1 and
D2 also protect against some overvoltage situations.
With Figure 5’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 results.
