In the normal mode the device is able to receive and to transmit messages whereas in

the receive-only mode signals at the TxD input are not transmitted to the CAN bus. The

receive-only mode can be used for diagnostic purposes (to check the bus connections

between the nodes) as well as to prevent the bus being blocked by a faulty permanent

dominant TxD input signal. The stand-by mode is a low power mode that disables both,

the receiver as well as the transmitter.

In case the receive-only feature is not used the RM pin has to be left open. When the

stand-by mode is not used the INH pin has to be connected to ground level in order to

switch the TLE6250G in normal mode.

Application Information for the 3.3 V Versions

The TLE6250GV33 can be used for both; 3.3 V and 5 V microcontroller logic supply, as

shown in Figure 6. Don’t apply external resistors between the power supply and this pin.

This may cause a voltage drop and so reduce the available voltage at this pin.
