The TLE6250G and TLE6250G-V33 are legacy Infineon high-speed CAN transceivers used between a CAN controller and the physical differential bus in automotive and industrial systems. Both support data rates up to 1Mbit/s, 12V and 24V system applications, low-power standby operation and a PG-DSO-8 surface-mount package.

Infineon currently lists both products as End of Life and discontinued. However, they are not identical devices. The most important difference is the microcontroller logic interface: TLE6250G is the 5V logic version, while TLE6250G-V33 includes a separate voltage-adaptive logic supply for 3.3V or 5V controllers.

TLE6250G vs TLE6250G-V33 Comparison

The Main Difference: 5V Logic vs Voltage-Adaptive Logic

TLE6250G is intended for a 5V CAN controller or microcontroller interface. Its TxD, RxD and control thresholds are referenced to the 5V VCC rail. Pin 5 is the RM input, which enables receive-only mode for diagnostics or for preventing a faulty dominant TxD signal from blocking the CAN bus.

TLE6250G-V33 still requires a 4.5V-to-5.5V VCC supply for the CAN transceiver. It adds a separate V33V logic-supply input on pin 5. Connecting that pin to the controller's 3.3V or 5V rail adapts the TxD, RxD and INH logic levels to the controller.

The V33 version therefore does not mean that the entire transceiver runs only from 3.3V. Both VCC and V33V must be connected according to the datasheet application circuit.

Are TLE6250G and TLE6250G-V33 Interchangeable?

No—not without checking the PCB and circuit operation. Although both devices use the same eight-pin package and share most signal locations, pin 5 has a different electrical function:

TLE6250G: pin 5 is the RM control input.

TLE6250G-V33: pin 5 is the V33V logic-supply input.

Substituting one version for the other could connect a control signal to a supply pin or remove the required logic rail. TLE6250G also provides receive-only mode, while TLE6250G-V33 does not. Buyers should match the complete ordering code to the approved BOM instead of treating the two names as suffix variations of the same component.

Frequently Asked Questions

Are TLE6250G and TLE6250G-V33 discontinued?

Yes. Infineon marks both product pages as End of Life and lists TLE6250GXUMA1 and TLE6250GV33XUMA1 as discontinued.

What is the main difference between the two versions?

TLE6250G uses 5V logic and assigns pin 5 to the RM receive-only control. TLE6250G-V33 assigns pin 5 to the V33V logic supply, allowing its digital interface to work with 3.3V or 5V controllers.

Can TLE6250G-V33 operate from only a 3.3V supply?

No. Its CAN transceiver VCC operating range is 4.5V to 5.5V. The separate V33V pin accepts 3.0V to 5.5V and sets the microcontroller-interface logic level.

Can TLE6250G directly replace TLE6250G-V33?

No. Pin 5 changes from a logic-supply input to the RM control input, and the available operating modes differ. A circuit review is required before any substitution.

What are the exact ordering codes?

The official tape-and-reel OPNs are TLE6250GXUMA1 and TLE6250GV33XUMA1. The second part is also commonly searched as TLE6250G-V33.

What are the recommended newer alternatives?

Infineon's product pages direct users to TLE9350BSJ for TLE6250G and TLE9350BVSJ for TLE6250G-V33. Both are active CAN FD devices, but full electrical and system validation is necessary.
