(2) All typical values are at VCC = 3.3 V or VCC = 5 V, and TA = 25°C. 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 VOH High-level output voltage DOUT at RL = 3 kΩ to GND, DIN = GND 5 5.4 V VOL Low-level output voltage DOUT at RL = 3 kΩ to GND, DIN = VCC –5 –5.4 V IIH High-level input current VI = VCC ±0.01 ±1 μA IIL Low-level input current VI = GND ±0.01 ±1 μA VCC = 3.6 V, VO = 0 V ±35 ±60 Short-circuit IOS mA output current(3) VCC = 5.5 V, VO = 0 V ±35 ±60 ro Output resistance VCC, V+, and V– = 0 V, VO = ±2 V 300 10M Ω VO = ±12 V, VCC = 3 V to 3.6 V ±25 Ioff Output leakage current FORCEOFF = GND μA VO = ±10 V, VCC = 4.5 V to 5.5 V ±25 (1) 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. (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 Maximum data rate CL = 1000 pF, RL = 3 kΩ, See Figure 1 150 250 kbit/s tsk(p) Pulse skew(3) CL = 150 pF to 2500 pF, RL = 3 kΩ to 7 kΩ, See Figure 2 100 ns Slew rate, CL = 150 pF to 1000 pF 6 30 VCC = 3.3 V, SR(tr) transition region V/ μs RL = 3 kΩ to 7 kΩ CL = 150 pF to 2500 pF 4 30 (see Figure 1) (1) 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. (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. 4 Submit Documentation Feedback |
