#Noise immunity specified for worst–case input combination.
Noise Margin for both "1" and "0" level =
1.0 Vdc min @ V DD = 5.0 Vdc
2.0 Vdc min @ V DD = 10 Vdc
2.5 Vdc min @ V DD = 15 Vdc
** The formulas given are for the typical characteristics only at 25 _ C.
†To calculate total supply current at loads other than 50 pF:
I T (C L ) = I T (50 pF) + 3.5 x 10 –3 (C L – 50) V DD f
where: I T is in µA (per package), C L in pF, V DD in Vdc, and f in kHz is input frequency.
