(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. switching characteristics 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, RL = 3 kΩ Maximum data rate 250 500 kbit/s One DOUT switching, See Figure 1 tsk(p) Pulse skew(3) CL = 150 pF to 2500 pF, RL = 3 kΩ to 7 kΩ, See Figure 2 100 ns VCC = 3.3 V, CL = 150 pF to 1000 pF 6 30 Slew rate, transition region SR(tr) RL = 3 kΩ to 7 kΩ, V/ µs (see Figure 1) CL = 150 pF to 2500 pF 4 30 PRR = 250 kbit/s (1) Test conditions are C1–C4 = 0.1 µF at V CC = 3.3 V + 0.3 V; C1 = 0.047 µF, C2–C4 = 0.33 µF at VCC = 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.
