1
TxD
2
GND
Transmit Data Input;
internal pull-up to V_IO, “low” for “dominant” state.
Ground
3
V_CC
Transceiver Supply Voltage;
100 nF decoupling capacitor to GND required.
4
RxD
Receive Data Output;
“low” in “dominant” state.
5
V_IO
Digital Supply Voltage Input;
supply voltage input to adapt the logical input and output voltage levels of the
transceiver to the microcontroller supply.
100 nF decoupling capacitor to GND required.
6
CANL
CAN Bus Low Level I/O;
“low” in “dominant” state.
7
CANH
CAN Bus High Level I/O;
“high” in “dominant” state.
8
NEN
Not Enable Input¹⁾;
internal pull-up to V_IO, “low” for normal-operating mode.
1) The designation of pin 8 is different in the TLE7250GVIO and its predecessor, the TLE6250GV33. The function of pin 8
remains the same.
