Table 4. Dynamic Electrical Characteristics (continued)
Characteristics noted under conditions 6.0 V ≤ V_PWR ≤ 27 V, 4.5 V ≤ V_DD ≤ 5.5 V, - 40°C ≤ T_A ≤ 125°C, GND = 0 V unless
otherwise noted. Typical values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions unless
otherwise noted.

Notes
21. Turn-ON delay time measured from rising edge of any signal (IN[0:3], SCLK, CS) that would turn the output ON to V_HS[0:3] = 0.5 V with
R_L = 5.0 Ω resistive load.
22. Turn-OFF delay time measured from falling edge of any signal (IN[0:3], SCLK, CS) that would turn the output OFF to V_HS[0:3] = V_PWR-
0.5 V with R_L = 5.0 Ω resistive load.
23. This logical bit is not defined. Do not use.
24. Time necessary for the CSNS to be with ±5% of the targeted value.
25. Watchdog timeout delay measured from the rising edge of WAKE or RST from a sleep state condition, to output turn-ON with the output
driven OFF and FSI floating. The values shown are for WDR setting of [00]. The accuracy of t _WDTO is consistent for all configured
watchdog time-outs.
