#Noise immunity specified for worst–case input combination.
Noise Margin for both “1” and “0” level =
1.0 Vdc min @ VDD = 5.0 Vdc
2.0 Vdc min @ VDD = 10 Vdc
2.5 Vdc min @ VDD = 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:
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 Vdc, and f in kHz is input frequency.
