12.Minimum signal delay time is measured from the TxD voltage threshold to CANH = 1.0 V. load should be min per the Timing Measurement
Load Conditions table.

BAT
= 27 V, CANH = 2.8 V at V
BAT

16.Maximum signal delay time is measured from the TxD voltage threshold to CANH = 1 V. load should be max per the Timing Measurement

17.Maximum signal delay time is measured from the TxD voltage threshold to CANH = 3.5 V. load should be max per the Timing Measurement
Load Conditions table.
18.Minimum signal delay time is measured from the TxD voltage threshold to CANH = 3.5 V. load should be min per the Timing Measurement
Load Conditions table.
19.Receive delay time is measured from the rising / falling edge crossing of the nominal V
ih
value on CANH to the falling (V
cmos_il_max
) / rising
(V
cmos_ih_min
) edge of RxD. This parameter is tested by applying a square wave signal to CANH. The minimum slew rate for the bus rising
and falling edges is 50 V/ s. The low level on bus is always 0 V. For normal mode and high-speed mode testing the high level on bus is 4 V.
For HVWU mode testing the high level on bus is V
BAT
- 2 V. Relaxation of this non-critical parameter from 0.15 s to 0.10 s may be addressed
in future revisions of GMW3089.
