LSF0108: What input impedance when EN pin=Low?

user4979899

Part Number: LSF0108

Hi Sir.

We are using LSF0108 for MDC/MDIO level shift 1.2V to 3.3V.

What input impedance of A1, A2 when EN pin=Low?

When the EN pin is pulled low, the internal switches never switch on, so the pins themselves have high impedance, and the two sides are disconnected.

However, the external pull-up resistors have a not-so-high impedance.
