AC Electrical Characteristics
VCC = 5V, TA = 25°C, CL = 15 pF, tr = tf = 6 ns
AC Electrical Characteristics
CL = 50 pF, tr = tf = 6 ns (unless otherwise specified)
Note 5: CPD determines the no load dynamic power consumption, PD = CPD VCC
2f
+ I
CC VCC, and the no load dynamic current consumption,
IS = CPD VCC f + ICC.
