#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
μ
A (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).
