TxD Time-Out

If the TxD signal is dominant for the time t >

t

stage. The device remains in recessive state. The TxD time-out functions prevents the LIN bus from being blocked

by a permanent LOW signal on the TxD pin, caused by a failure. The transmitter output stage is released again,

after a rising edge on the TxD pin has been detected (see Figure 12).

LIN Specifications

The LIN network is standardized by international regulations. The devices TLE8458G and the TLE8458GV33 are

compliant to the specification LIN 2.1. The physical layer specification LIN 2.1 is a super set of the previous LIN

specifications, like LIN 2.0 or LIN 1.3. The TLE8458G and the TLE8458GV33 have been qualified according to

the LIN 2.1 standard, conformance test results are available on request.
