VSUP, VDD, 5V-CAN: shorted to GND, or connected to GND via a 47 k resistor instances are guaranteed by design and device characterization. 22. Guaranteed by design and device characterization. Table 4. Static Electrical Characteristics (continued) Characteristics noted under conditions 5.5 V ≤ VSUP ≤ 28 V, -40 °C ≤ TA ≤ 125 °C, unless otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25 °C under nominal conditions, unless otherwise noted. Characteristic Symbol Min Typ Max Unit |
