All typical are given for VcQ-5V and Ta = 250C NoYe 2: Skewisadefined as the difference in propagation delays between complementary outputs at the 50% point. Note 3: Output disable time is the de n the 'ontr:put,bt:j: gf t:_hIRd72\?_t,h_ , tp:t transistors tuming off. The actual disable times are less thu:~uindicated due to thjaSd9dl:a:y frdd c\hby RC time :Vcc, and the no load dynamic current consu mption Note 4: CPD determines the no load dynamic power consumption, PD = CPD Vzccf = lccVc PD = CPD Vccf+lcc | SYMBOL | PARAMETER | CONDITIONS | TYP | MAX | UNIT | | Rtr, j-mb | Junction to mounting base | | | 3.0 | K/W | | Rtr,ia | Junction to ambient | in free air | 1 00 | | K/W | | | | | | |
