AC Electrical Characteristics
VCC = 5V, TA = 25°C, CL = 15 pF, tr = tf = 6ns.
AC Electrical Characteristics
CL = 50 pF, tr = tf = 6ns (unless otherwise specified).
Notes:
3. 4 levels of delay are A to Y1, Y3 and B to Y2, Y3.
4. 5 levels of delay are A to Y0, Y2 and B to Y0, Y1.
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.
