Description

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
translated voltage
Input B supply
2.5V 3.3V 5V
1V A A A
1.2V A A A
1.8V P A A
2.5V P P A
3,3V P P A

A – Allowed configuration
P – Prohibited configuration. It won’t work.

This multpile channel voltage level translator can be used with interfaces: SPI, I2C/TWI, UART or standard logic IO. Example system configurations are showed in the picture:
