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 circuit. For proper operation, Vin and Vout should be constrained to the range VSS (Vin or Vout) VDD for control inputs and VEE ≤ (Vin or Vout) ≤ VDD for Switch I/O. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS, VEE or VDD). Unused outputs must be left open.

For voltage drops across the switch (∆Vswitch) > 600 mV ( > 300 mV at high temperature), excessive VDD current may be drawn; i.e. the current out of the switch may contain both VDD and switch input components.

If voltage transients above VDD and/or below VEE are anticipated on the analog channels, external diodes (Dx) are recommended as shown in Figure B. These diodes should be small signal types able to absorb the maximum anticipated current surges during clipping. The absolute maximum potential difference between VDD and VEE is 18.0 volts. Most parameters are specified up to 15 volts which is the recommended maximum difference between VDD and VEE. Balanced supplies are not required. However, V SS must be greater than or equal to VEE. For example, VDD = + 10 volts, VSS = + 5 volts, and VEE = – 3 volts is acceptable. See the table below. Figure A illustrates use of the on–chip level converter detailed in Figure 2. The 0–to–5 volt Digital Control signal is used to directly control a 9 Vp–p analog signal. The digital control logic levels are determined by VDD and VSS. The VDD voltage is the logic high voltage; the VSS voltage is logic low. For the example, VDD = + 5 V = logic high at the control inputs; V SS = GND = 0 V = logic low. The maximum analog signal level is determined by V DD and VEE. The VDD voltage determines the maximum recommended peak above VSS. The VEE voltage determines the maximum swing below VSS. For the example, VDD – VSS = 5 volt maximum swing above VSS; VSS – VEE = 5 volt maximum swing below VSS.
