Working Principles

The SN74LVTH126PWRE4 is a logic level translator that facilitates communication between devices operating at different voltage levels. It utilizes a combination of CMOS and TTL technologies to achieve bidirectional voltage translation.

The device consists of four independent channels, each capable of translating signals from one voltage level to another. The input voltage levels can be as low as 1.65V and as high as 3.6V, while the output voltage levels are compatible with both TTL and CMOS logic.

By enabling the appropriate channel using the OE pin, the input signal is translated to the corresponding output voltage level. The device supports both push-pull and open-drain outputs, providing flexibility in various applications.
