#Noise immunity specified for worst–case input combination.
Noise Margin for both “1” and “0” level = 1.0 V min @ VDD = 5.0 V
= 2.0 V min @ VDD = 10 V
= 2.5 V min @ VDD = 15 V
†To calculate total supply current at loads other than 50 pF:
IT(CL) = IT(50 pF) + 3.5 x 10–3 (CL – 50) VDDf
where: IT is in µA (per package), CL in pF, VDD in V, and f in kHz is input frequency.
** The formulas given are for the typical characteristics only at 25_C.
This device contains 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 applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation it is recommended that Vin and Vout be constrained to the range VSS ≤ (Vin or
Vout) ≤ VDD.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD).
