Reception
The analog CAN bus signals are converted into a digital signal at RxD via the differential input
receiver. The RxD signal is switched to RxD output pin via the multiplexer (MUX), see
In normal mode the split pin is used to stabilize the recessive common mode signal.
Standby Mode
The standby mode is designed to switch the TLE6251DS into a low power mode with minimum
current consumption. The driving stages and the receiver are deactivated. Only the relevant
circuitry to guarantee a correct handling of the CAN bus wake-up is still active. This wake-up
receiver is also designed to show an excellent immunity against electromagnetic noise (EMI).
Change into Standby Mode during CAN Bus Failure
It is possible to change from normal mode into the standby mode if the bus is dominant due to a
bus failure without setting the RxD wake flag to LOW. The advantage is, that the TLE6251DS
can be kept in the standby mode even if a bus failure occurs.

dominant. Normal communication is not possible until the failure is removed. To reduce the
current consumption, it makes sense to switch over to standby mode. This is possible with the
