TCA5405: min/max switching frequency

Kai Nomiyama

Part Number: TCA5405

Hi Team,

When I take a look at timing requirement of TCA5405, it looks fMIN and fMAX is the other way around.
Is following correct?
fmax Maximum switching frequency on DIN 1MHz_min
fmin Minimum switching frequency on DIN 10kHz_max
frequency range 10k to 1MHz

Regards,
Kai

    Hey Kai,

    "frequency range 10k to 1MHz"

    This is correct.

    "fmax Maximum switching frequency on DIN 1MHz_min
    fmin Minimum switching frequency on DIN 10kHz_max"

    The way I interprete this is that we guarantee that our device will work at 1MHz minimum (for the maximum speed). So you may find devices which operate faster than 1MHz but we guarantee that all devices should hit at least 1MHz in frequency. [ The maximum minimum frequency]

    The inverse is true for the lower frequency parameter.

    Thanks,
