Table 4. Dynamic Electrical Characteristics
All characteristics are for the analog chip only. Please refer to the 68HC908EY16 data sheet for characteristics of the
microcontroller chip. Characteristics noted under conditions 9.0 V VSUP 16 V, -40 °C TJ 125 °C, unless otherwise noted.
Typical values noted reflect the approximate parameter mean at TA = 25 °C under nominal conditions, unless otherwise noted.

Notes
19.
VSUP from 7.0 V to 18 V, bus load R0 and C0 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.
20.
21.
22.
Measured between LIN signal threshold VIL or VIH and 50% of RXD signal.
23.
tWAKE is typically 2 internal clock cycles after LIN rising edge detected. See Figure 8 and Figure 9, page 15. In Sleep mode the VDD
rise time is strongly dependent upon the decoupling capacitor at VDD pin.
