(2) All typical values are at VCC = 3.3 V or VCC = 5 V, and TA = 25°C. (3) Short-circuit durations should be controlled to prevent exceeding the device absolute power dissipation ratings, and not more than one output should be shorted at a time. over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (see Figure 6) PARAMETER TEST CONDITIONS MIN TYP(2) MAX UNIT CL = 1000 pF 250 Maximum data rate RL = 3 kΩ, CL = 250 pF, VCC = 3 V to 4.5 V 1000 kbit/s (see Figure 1) One DOUT switching CL = 1000 pF, VCC = 4.5 V to 5.5 V 1000 tsk(p) Pulse skew(3) CL = 150 pF to 2500 pF, RL = 3 kΩ to 7 kΩ, See Figure 2 25 ns Slew rate, SR(tr) transition region CL = 150 pF to 1000 pF, RL = 3 kΩ to 7 kΩ, VCC = 3.3 V 18 150 V/ µs (see Figure 1) (1) Testing supply conditions are C1–C4 = 0.1 µF at V CC = 3.3 V ± 0.15 V; C1–C4 = 0.22 µF at VCC = 3.3 V ± 0.3 V; and C1 = 0.047 µF and C2–C4 = 0.33 µF at V CC = 5 V ± 0.5 V. (2) All typical values are at VCC = 3.3 V or VCC = 5 V, and TA = 25°C. (3) Pulse skew is defined as |tPLH – tPHL| of each channel of the same device.
