This device contains protection circuitry guard against damage high static voltages electric fields. However, precautions must taken avoid applications voltage higher than maximum rated voltages this high-impedance circuit. proper operation, Vout should constrained range (Vin Vout) VCC. Unused inputs must always tied appropriate logic voltage level (e.g., either VCC). Unused outputs must left open.
Maximum Ratings those values beyond which damage device occur. Functional operation should restricted Recommended Operating Conditions. Derating Plastic DIP: mW/_C from 125_C high frequency heavy load considerations, Chapter Motorola High-Speed CMOS Data Book (DL129/D).
