LSF0102: what's the difference between PCA9306 and LSF0102?

Part Number: LSF0102
Other Parts Discussed in Thread: PCA9306, , TCA9406, TXS0102

Hi Dear expert,

We notice that PCA9306 and LSF0102 spec/package is very similar, we would like to know these two devices difference, would you please help clarify?

Thanks very much for your support!

BR,

Joyce

    There are three differences:

    • the marking painted on top of the chip;
    • smaller reels are available for the PCA; and
    • the price.

    (In most applications that translate between exactly two voltages, the PCA9306/LSF0102 can be replaced with the TCA9406/TXS0102, which needs fewer external components.)

    So specs are all the same, right?
    thanks a lot for your reply.

    Hi Joyce,

    The PCA9306 belongs to another (Interface) group. The PCA9306 is optimized for I2C operation, whereas the LSF0102 is a generic translator though they have similiar architecture.
    The PCA is qualified for 85C as listed in the datasheet vs 125C for the LSF.
    The testing on the LSF and PCA device are also different with different limits as you can see on the datasheet.( ron, tpd etc).
    As Clemens mentioned, you can also consider using TXS0102 which have built in resistors suited for I2C operation saving on BOM space and costs. Let me know if you have anything else.
