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 MIN NOM MAX UNIT VCC Supply voltage 4.5 5 5.5 V VIH High-level input voltage (T1IN,T2IN) 2 V VIL Low-level input voltage (T1IN, T2IN) 0.8 V R1IN, R2IN Receiver input voltage ±30 V TA Operating free-air temperature MAX232 0 70 °C TA Operating free-air temperature MAX232I −40 85 °C electrical characteristics over recommended ranges of supply voltage and operating free-air temperature (unless otherwise noted) (see Note 4 and Figure 4) PARAMETER TEST CONDITIONS MIN TYP‡ MAX UNIT ICC Supply current VCC = 5.5 V, TA = 25°C All outputs open, 8 10 mA ‡ All typical values are at VCC = 5 V and TA = 25°C.
