RT-NVT2008 is a bidirectional voltage level translator. Signal pass IC both ways seamlessly without need of control transmission direction.
Input voltage drives translator high side (VrefB) and a low voltage regulator (VrefA) which can also be sourced on VL pin. Boards are supplied with fixed voltage regulator: 1V/1.2V/1.8V/2.5V/3.3V/5.0V. Output voltage should be selected to supply lower voltage side with minimum voltage difference between VrefB and VrefA:
(V_Input_B - V_Input_A) >= 1V.
See comparison of the correct voltages in the table below:
|Input A minimum
|Input B supply|
A – Allowed configuration
P – Prohibited configuration. It won’t work.
