DYNAMIC ELECTRICAL CHARACTERISTICS
Table 5. Dynamic Electrical Characteristics (continued)
Characteristics noted under conditions of -40°C ≤ T_A ≤ 125°C, unless otherwise stated. Voltages are relative to GND unless
otherwise noted. All positive currents are into the terminal. All negative currents are out of the terminal.

High-Voltage Rising Output Delay
200 Ω ≤ R_L ≤ 3332 Ω, 1.0 µs ≤ Load Time Constants ≤ 4.0 µs
Measured from TXD=V_IL to V_BUS as follows:
Max Time to V_BUSMOD = 3.7 V, 6.0 V ≤ V_BATT ≤ 26.5 V ⁽¹⁴⁾
Min Time to V_BUSMOD = 1.0 V, 6.0 V ≤ V_BATT ≤ 26.5 V ⁽¹⁴⁾
Max Time to V_BUSMOD = 9.4 V, 12.0 V ≤ V_BATT ≤ 26.5 V ⁽¹⁴⁾
High-Voltage Falling Output Delay
200 Ω ≤ R_L ≤ 3332 Ω, 1.0 µs ≤ Load Time Constants ≤ 4.0 µs,
12.0 V ≤ V_BATT ≤ 26.5 V
