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.
