These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltages are with respect to network GND. 2. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. 3. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions (see Note 4 and Figure 6) MIN NOM MAX UNIT Supply voltage VCC = 3.3 V 3 3.3 3.6 V Supply voltage VCC = 5 V 4.5 5 5.5 V VIH Driver and control high-level input voltage DIN, FORCEOFF, FORCEON VCC = 3.3 V 2 V VIH Driver and control high-level input voltage DIN, FORCEOFF, FORCEON VCC = 5 V 2.4 V VIL Driver and control low-level input voltage DIN, FORCEOFF, FORCEON 0.8 V VI Driver and control input voltage DIN, FORCEOFF, FORCEON 0 5.5 V VI Receiver input voltage −25 25 V TA Operating free-air temperature SN65C3243 −40 85 °C TA Operating free-air temperature SN75C3243 0 70 °C NOTE 4: 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. electrical characteristics over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (see Note 4 and Figure 6) PARAMETER TEST CONDITIONS MIN TYP‡ MAX UNIT II Input leakage current FORCEOFF, FORCEON ±0.01 ±1 µA Auto-powerdown disabled No load, FORCEOFF and FORCEON = VCC 0.3 1 mA I Supply current Powered off No load, FORCEOFF = GND 1 10 ICC Supply current Auto-powerdown enabled No load, FORCEOFF = VCC, FORCEON = GND, All RIN are open or grounded, All DIN are grounded 1 10 µA ‡ All typical values are at VCC = 3.3 V or VCC = 5 V, and TA = 25°C.
