LSF0108-Q1: LSF0108-Q1 schematic check

Part Number: LSF0108-Q1

Hi, Support Team

We use TI device LSF0108-Q1, Could help to check schematic is okay?

1. Please check Vref_A/Vref_B/ EN is okay?

2. we also use different pull high voltage, the schematic is okay?

If any suggestion, Please advise me.

Thanks,

Best regards,

Lawrence

  • 1. Vref/EN are OK.

    2. Different pull-up voltages are OK, as long as they are not below Vref_A (1.8 V).

    The pull-up resistors on the left side are extremely strong. This increases the low-level voltage and the power usage, and is not needed (especially for I²C) except for very-high-speed signals.
