ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ *For voltage drops across the switch greater than 1.2 V (switch on), excessive VCC current may

ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ be drawn; i.e., the current out of the switch may contain both VCC and switch input

components. The reliability of the device will be unaffected unless the Maximum Ratings are

exceeded.

This device contains protection

circuitry to guard against damage

due to high static voltages or electric

fields. However, precautions must

be taken to avoid applications of any

voltage higher than maximum rated

voltages to this high−impedance cir-

cuit. For proper operation, Vin and

Vout should be constrained to the

range GND v (Vin or Vout) v VCC.

Unused inputs must always be

tied to an appropriate logic voltage

level (e.g., either GND or VCC).

Unused outputs must be left open.

I/O pins must be connected to a

properly terminated line or bus.
