6.10 Switching Characteristics: Driver

over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted)(3)
PARAMETER TEST CONDITIONS MIN TYP(1) MAX UNIT
Maximum data rate CL = 1000 pF, RL = 3 kΩ, 150 250 kbit/s
tsk(p) Pulse skew(2) CL = 150 pF to 2500 pF, RL = 3 kΩ to 7 kΩ, See Figure 7-2 100 ns
SR(tr) Slew rate,
transition region
(see Figure 7-1)		 VCC = 3.3 V,
RL = 3 kΩ to 7 kΩ		 CL = 150 pF to 1000 pF 6 30 V/µs
CL = 150 pF to 2500 pF 4 30
(1) All typical values are at VCC = 3.3 V or VCC = 5 V, and TA = 25°C.
(2) Pulse skew is defined as |tPLH  – tPHL| of each channel of the same device.
(3) Test conditions are C1–C4 = 0.1 µF at VCC = 3.3 V ± 0.3 V; C1 = 0.047 µF, C2–C4 = 0.33 µF at VCC = 5 V ± 0.5 V.
