Product data sheet
7.1 Enable and disable
The NVT2001/02 can be used in level translation applications for interfacing devices or
systems operating at different interface voltages with one another. The NVT2001/02 is
ideal for use in applications where an open-drain driver is connected to the data I/Os. The
NVT2001/02 can also be used in applications where a push-pull driver is connected to the
data I/Os.
The NVT20xx has an EN input that is used to disable the device by setting EN LOW,
which places all I/Os in the high-impedance state.
