#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.
