7 / 26 page ![]() 7.6 Electrical Characteristics over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (see Figure 10-1) PARAMETER TEST CONDITIONS(1) MIN TYP(2) MAX UNIT II Input leakage current FORCEOFF, FORCEON, EN ±0.01 ±1 μA ICC Supply current (TA = 25°C) Auto-powerdown disabled No load, FORCEOFF and FORCEON at VCC 0.3 1 mA Powered off No load, FORCEOFF at GND 1 10 μA Auto-powerdown enabled No load, FORCEOFF at VCC, FORCEON at GND, All RIN are open or grounded 1 10 (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. 7.7 Driver Section: Electrical Characteristics over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (see Figure 10-1) PARAMETER TEST CONDITIONS(1) 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 at GND ±0.01 ±1 μA IOS Short-circuit output current(3) VCC = 3.6 V, VO = 0 V ±35 ±60 mA VCC = 5.5 V, VO = 0 V ±35 ±90 ro Output resistance VCC, V+, and V– = 0 V, VO = ±2 V 300 10M Ω Ioff Output leakage current FORCEOFF = GND VO = ±12 V, VCC = 3 V to 3.6 V ±25 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. 7.8 Switching Characteristics: Driver over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (see Figure 10-1) PARAMETER TEST CONDITIONS(1) MIN TYP(2) MAX UNIT Maximum data rate (see Figure 8-1) RL = 3 kΩ CL = 1000 pF 250 kbit/s CL = 250 pF, VCC = 3 V to 4.5 V 1000 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 8-2 100 ns SR(tr) Slew rate, transition region (see Figure 8-1) VCC = 3.3 V, RL = 3 kΩ to 7 kΩ, CL = 150 pF to 1000 pF 18 150 V/μs (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. www.ti.com SN65C3221E, SN75C3221E SLLS694C – NOVEMBER 2005 – REVISED JULY 2021 Copyright © 2021 Texas Instruments Incorporated Submit Document Feedback 7 Product Folder Links: SN65C3221E SN75C3221E |
