Switching Characteristics: Driver

over recommended operating conditions (unless otherwise noted)
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
tPLH Propagation delay time, recessive-to-dominant output See Figure 10 31 74 110 ns
tPHL Propagation delay time, dominant-to-recessive output 25 44 75
tr Differential output signal rise time 20 50
tf Differential output signal fall time 20 50
tTXD_DTO(1) Dominant time-out ↓ CL=100 pF, See Figure 16 300 450 700 μs
The TXD dominant time out (tTXD_DTO) disables the driver of the transceiver once the TXD has been dominant longer than (tTXD_DTO) which releases the bus lines to recessive preventing a local failure from locking the bus dominant. The driver may only transmit dominant again after TXD has been returned HIGH (recessive). While this protects the bus from local faults locking the bus dominant it limits the minimum data rate possible. The CAN protocol allows a maximum of eleven successive dominant bits (on TXD) for the worst case where five successive dominant bits are followed immediately by an error frame. This along with the (tTXD_DTO) minimum limits the minimum bit rate. The minimum bit rate may be calculated by: Minimum Bit Rate = 11/ (tTXD_DTO) = 11 bits / 300 µs = 37 kbps.
