Working Principles

The SN74LVC841ADGVR is designed using low-voltage CMOS technology, which allows it to operate over a wide supply voltage range. It functions as an 8-bit non-inverting translator, enabling bidirectional voltage translation between two logic levels. The device features separate output enable (OE#) inputs for each direction, allowing independent control of the translation.

When the OE# input is low, the device is enabled, and the voltage translation occurs based on the logic levels applied to the A1/B1 and A2/B2 inputs. The translated output appears on the Y1/Y2 pins. When the OE# input is high, the device is disabled, and the outputs are in a high-impedance state.
