Table 34. Dynamic Electrical Characteristics (continued)
Characteristics noted under conditions 5.5 V ≤ VSUP ≤ 18 V, -40°C ≤ TA ≤ 125°C for the 33910 and -40°C ≤ TA ≤ 85°C for the
34910, unless otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under nominal
conditions, unless otherwise noted.

Notes
112. VSUP from 7.0 V to 18 V, bus load RBUS and CBUS 1.0 nF / 1.0 kΩ, 6.8 nF / 660 Ω, 10 nF / 500 Ω. Measurement thresholds: 50% of TXD
signal to LIN signal threshold defined at each parameter. See Figure 6.
113. See Figure 9.
114. See Figure 10, for Sleep and Figure 11, for Stop mode.
115. The measurement is done with 1.0 µF capacitor and 0 mA current load on VDD. The value takes into account the delay to charge the
capacitor. The delay is measured between the bus wake-up threshold (VBUSWU) rising edge of the LIN bus and when V reaches 3.0 V.
DD
See Figure 10. The delay depends of the load and capacitor on VDD
.
116. In Stop mode, the delay is measured between the bus wake-up threshold (VBUSWU) and the falling edge of the IRQ pin. See Figure 11.
117. This parameter is guaranteed by process monitoring but, not production tested.
