Product data sheet Rev. 5 — 19 October 2011 6 of 16 NXP Semiconductors 74LVC139 Dual 2-to-4 line decoder/demultiplexer [1] All typical values are measured at VCC = 3.3 V (unless stated otherwise) and Tamb =25 C. 10. Dynamic characteristics [1] Typical values are measured at Tamb =25 C and VCC = 1.2 V, 1.8 V, 2.5 V, 2.7 V, and 3.3 V respectively. [2] tpd is the same as tPLH and tPHL. [3] Skew between any two outputs of the same package switching in the same direction. This parameter is guaranteed by design. [4] 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, ICC supply current VCC = 3.6 V; VI =VCC or GND; IO =0A -0.1 10 -40 A I CC additional supply current per input pin ; VCC = 2.7 V to 3.6 V; VI =VCC 0.6 V; IO =0A - 5 500 - 5000 A CI input capacitance VCC = 0 V to 3.6 V; VI =GND to VCC - 5.0 -- -pF Table 6.
