Product data sheet Rev. 3 — 31 January 2013 8 of 15 NXP Semiconductors 74AVC16245 16-bit transceiver with direction pin; 3.6 V tolerant; 3-state 10. Dynamic characteristics [1] tpd is the same as tPLH and tPHL. ten is the same as tPZL and tPZH. tdis is the same as tPLZ and tPHZ. [2] Typical values are measured at Tamb =25 C and VCC = 1.2 V, 1.5 V, 1.8 V, 2.5 V and 3.3 V respectively. [3] 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 Volts N = number of inputs switching (C L VCC 2 f o) = sum of the outputs. Table 7. Dynamic characteristics Voltages are referenced to GND (ground = 0 V). For test circuit see Figure 8.
