DYNAMIC ELECTRICAL CHARACTERISTICS

Table 5. Dynamic Electrical Characteristics (continued)

Characteristics noted under conditions of -40°C ≤ TA ≤ 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 ≤ RL ≤ 3332 Ω, 1.0 µs ≤ Load Time Constants ≤ 4.0 µs

Measured from TXD=VIL to VBUS as follows:

Max Time to VBUSMOD = 3.7 V, 6.0 V ≤ VBATT ≤ 26.5 V (14)

Min Time to VBUSMOD = 1.0 V, 6.0 V ≤ VBATT ≤ 26.5 V (14)

Max Time to VBUSMOD = 9.4 V, 12.0 V ≤ VBATT ≤ 26.5 V (14)

High-Voltage Falling Output Delay

200 Ω ≤ RL ≤ 3332 Ω, 1.0 µs ≤ Load Time Constants ≤ 4.0 µs,

12.0 V ≤ VBATT ≤ 26.5 V

Measured from TXD=VIH to VBUS as follows:

Max Time to VBUSMOD = 1.0 V (14)

Min Time to VBUSMOD = 3.7 V (14)
