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 4. 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 mA (per package), CL in pF, VDD in V, and f in kHz is input frequency. 5. The formulas given are for the typical characteristics only at 25 _C. |
