Dynamic characteristics [1] tpd is the same as tPLH and tPHL; tdis is the same as tPLZ and tPHZ; ten is the same as tPZL and tPZH. ten is a calculated value using the formula shown in Section 13.4 “Enable times” [1] tpd is the same as tPLH and tPHL; tdis is the same as tPLZ and tPHZ; ten is the same as tPZL and tPZH. ten is a calculated value using the formula shown in Section 13.4 “Enable times” [1] 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 = load capacitance in pF; VCC = supply voltage in V; N = number of inputs switching; (C L VCC 2 f o) = sum of the outputs.
