A transition from logical “High” to logical “Low” on the EN pin changes the operation mode from Normal Operation
mode to Sleep mode. If the TLE7269G is already in Sleep mode, changing the EN from “Low” to “High” results into
a mode change from Sleep mode to Normal Operation mode. If the device is in Stand-By mode a change from
“Low” to “High” on the EN pin changes the mode to Normal Operation mode (see

communication to the LIN bus is possible. The internal bus termination remains active as well as the INH pins (see
