FAQ

What is the purpose of the parallel hold mode?

The parallel hold mode retains the last valid data state at the outputs even when the device is disabled, preventing undefined states on the bus.

How does controlled slew rate benefit the circuit?

Controlled slew rates reduce signal reflections and electromagnetic interference (EMI) by slowing down the transition edges of the output signals.
