NVT2003/04/06
Bidirectional voltage-level translator
7.
Application design-in information
The NVT2003/04/06 can be used in level translation applications for interfacing devices or
systems operating at different interface voltages with one another. The NVT2003/04/06 is
ideal for use in applications where an open-drain driver is connected to the data I/Os. The
NVT2003/04/06 can also be used in applications where a push-pull driver is connected to
the data I/Os.
7.1 Enable and disable
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.
[1]
All typical values are at Tamb =25 C.
(1) The applied voltages at Vref(A) and Vpu(D) should be such that Vref(B) is at least 1 V higher than
Vref(A) for best translator operation.
