11 / 34 page Analog Integrated Circuit Device Data Freescale Semiconductor 11 33988 ELECTRICAL CHARACTERISTICS DYNAMIC ELECTRICAL CHARACTERISTICS DYNAMIC ELECTRICAL CHARACTERISTICS Table 4. Dynamic Electrical Characteristics Characteristics noted under conditions 4.5V ≤ V DD ≤ 5.5V, 6.0V ≤ VPWR ≤ 27V, -40°C ≤ TA ≤ 125°C, unless otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal conditions, unless otherwise noted.

Rise and Fall Slew Rates A measured across a 5.0 Ω resistive load at high side output = 0.5V to V PWR - 3.5V. These parameters are guaranteed by process monitoring. 19. Rise and Fall Slew Rates B measured across a 5.0 Ω resistive load at high side output = V PWR - 3.5V to VPWR - 0.5V. These parameters are guaranteed by process monitoring. 20. Turn-ON delay time measured from rising edge of IN[0:1] signal that would turn the output ON to VHS[0:1] = 0.5V with RL = 5.0Ω resistive load. 21. Turn-OFF delay time measured from falling edge that would turn the output OFF to VHS[0:1] = VPWR -0.5V with RL = 5.0Ω resistive load. |
