74LV393-Q100

Dual 4-bit binary ripple counter

[1]

All typical values are measured at Tamb = 25 C.

[2]

Typical values are measured at VCC = 3.3 V.

[3]

tpd is the same as tPLH and tPHL.

[4]

tt is the same as tTHL and tTLH.

CPD is used to determine the dynamic power dissipation (PD in W).

PD =CPD  VCC2  fi  N+ (CL  VCC2  fo) where:

fi = input frequency in MHz;

fo = output frequency in MHz;

CL = output load capacitance in pF;

VCC = supply voltage in V;

N = number of inputs switching;

(C
