TCAN1042V-Q1: TCAN1042 variant differences? H? V? HV? -Q1?

Part Number: TCAN1042V-Q1
Other Parts Discussed in Thread: TCAN1051, TCAN1051HV-Q1

Can someone explain the differences between the different variants of the TCAN1042

H? V? HV? -Q1?

some seem to be out of stock or others are available

a comparison in search shows no differences other than slight variations in package and price

    G indicates 5 Mbps.
    H indicates ±70 V bus fault protection.
    V indicates I/O level shifting.
    Q1 indicates AEC-Q100 qualification.

    This is shown in the Device Comparison Table in the datasheet.

    C,

    Thanks for bringing this to E2E. If you look in the electrical characteristics and pinout sections of the datasheet, these variants are explained.

    -V: Versions with the -V suffix have a VIO pin which allows the transceiver to work with 3.3V logic levels on TXD, RXD, and STB rather than just 5V

    -H: Versions with the -H suffix have extended CAN bus voltage protection, +/-70V rather than +/-58V in the non-H versions

    -Q1: Q1 means that the device was qualified under the AEC-Q100 definition for qualification for Automotive standards

    Please let me know if you have any questions.

    Regards,

    thx, for what i was intending i think i only need one that has a V however they all appear to be out of stock, are there any others that are functionally equivalent, i can ask as a separate question if needed

    C,

    TCAN1051 has the same function besides pin 8. On TCAN1042 pin 8 controls standby mode which disables the CAN bus driver and receiver when a logic high is applied to the pin. On TCAN1051 pin 8 controls silent mode which only disables the CAN bus driver when a logic high is applied to the pin.

    The TCAN1051V is likely out of stock too, but I think last time I checked the TCAN1051HV-Q1 had some devices in stock.

    Regards,
