7.6 Switching Characteristics

over operating free-air temperature range (unless otherwise noted)

PARAMETER		TEST CONDITIONS	MIN	TYP	MAX	UNIT
AC CHARACTERISTICS
t_{rx_pdr}	Receiver rising propagation delay time (ISO 17987-4 Param 31)	R_RXD = 2.4 kΩ, C_RXD = 20 pF (see Figure 7-2 and Figure 8-1)			6	μs
t_{rx_pdf}	Receiver falling propagation delay time (ISO 17987-4 Param 31)	R_RXD = 2.4 kΩ, C_RXD = 20 pF (see Figure 7-2 and Figure 8-1)			6	μs
t_{rx_sym}	Symmetry of receiver propagation delay time (ISO 17987-4 Param 32)	Rising edge with respect to falling edge (t_{rx_sym} = t_{rx_pdf} - t_{rx_pdr}) R_RXD = 2.4 kΩ, C_RXD = 20 pF (see Figure 7-2 and Figure 8-1)	–2		2	μs
t_NWake	NWake filter time for local wakeup	See Figure 7-6	25	50	150	μs
t_LINBUS	LIN wake-up time (Minimum dominant time on LIN bus for wakeup)	See Figure 9-2, Figure 9-3, and Figure 7-5	25	100	150	μs
t_CLEAR	Time to clear false wake-up prevention logic if LIN Bus had bus stuck dominant fault (recessive time on LIN bus to clear bus stuck dominant fault)	See Figure 9-3	8	17	50	μs
t_DST	Dominant state time-out⁽¹⁾		20	34	80	ms
t_{MODE_} _CHANGE	Mode change delay time	Time to change from standby mode to normal mode or normal mode to sleep mode through EN pin			5	μs

(1) TXD Dominant state timeout limits the minimum data rate to 650 bps. The minimum datarates may be calculated by the following forumulas. DataRate_{Commander(min)} = t_{SYNC_DOM(max)} / t_DST(min) and DataRate_{Responder(min)} = 9 + n_margin / t_DST(min) where n_margin is a safety margin. For responder node cases where n_margin ≤ 4, the commander node case will be the limiting calculation.
