The receive threshold values Vthr_max and Vthr_min are
symmetrical to 0.5*VSUP with a hysteresis of 0.135*VSUP.
The LIN specific receive threshold is between 0.4*VSUP
and 0.6 * VSUP.
Data Rate
The NCV7361A is a constant slew rate transceiver. The
bus driver works with a fixed slew rate range of 1.0 V/
ms
v DV/DT v 2.5 V/ms. This principle provides good
symmetry of the slope times between recessive to dominant
and dominant to recessive slopes within the LIN bus load
range (CBUS, Rterm).
The NCV7361A guarantees data rates up to 20 kb within
the complete bus load range under worst case conditions.
The constant slew rate principle holds appropriate voltage
levels and can operate within the LIN Protocol
Specification for RC oscillator systems with a matching
tolerance up to
"2% between 2 nodes.
TxD Input
The 5.0 V input TxD directly controls the BUS level:
TxD = low
→ BUS = low (dominant level)
TxD = high
→ BUS = high (recessive level)
The TxD pin has an internal pullup resistor connected to
VOUT. This guarantees that an open TxD pin generates a
recessive BUS level.
