UTC MC14511
CMOS IC
This device contains protection circuitry to protect the inputs against damage due to high static voltages or electric
fields. However, it is advised that normal precautions be taken to avoid application of any voltage higher than
maximum rated voltages to this high-impedance circuit. A destructive high current mode may occur if Vin and Vout are
not constrained to the range:
VSS ≤ (Vin or Vout) ≤ VDD.
Due to the sourcing capability of this circuit, damage can occur to the device if VDD is applied, and the outputs are
shorted to VSS and are at a logical 1 (See Maximum Ratings).
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD).
