trx_sym Symmetry of receiver propagation delay time Receiver rising propagation delay time (ISO/DIS 17987 Param 32) Rising edge with respect to falling edge, (trx_sym = trx_pdf – trx_pdr), RRXD = 2.4 kΩ, CRXD = 20 pF (Figure 8-12, Figure 8-13 and Figure 8-17) –2 2 µs
tLINBUS LIN wakeup time (minimum dominant time on LIN bus for wakeup) See Figure 8-16, Figure 9-3 and Figure 9-4  25 100 150 µs
tCLEAR Time to clear false wakeup prevention logic if LIN bus had a bus stuck dominant fault (recessive time on LIN bus to clear bus stuck dominant fault) See Figure 9-4 8 17 50 µs
tTXD_DTO Dominant state time out 20 34 80 ms
tEN Enable pin deglitch time Time enable pin state change before initiating mode change or sampling TXD pine: See Figure 8-14 3 12 µs
tMODE_CHANGE Mode change delay time normal mode to sleep or standby mode Time to change from normal mode to sleep or standby after TXD pin sampling after EN pin set low: See Figure 8-14 20 µs
tMODE_CHANGE Mode change delay time sleep mode to normal mode Time to change from sleep mode to normal mode through EN pin and not due to a wake event; RXD pulled up to VCC: See Figure 8-14 400 µs
