Product Description

LSF0204QPWRQ1 uses pass transistors rather than actively driving both sides of the interface. Pull-up rails and resistors determine high levels and rise time, allowing different channel voltages within the documented bias arrangement.

Its bidirectional architecture can translate open-drain buses as well as push-pull signals. The advertised speed depends on loading and pull-up sizing, so it is not a load-independent clock rating.
