Working Principles

The SN74CB3Q6800PWG4 is a bidirectional voltage level translator that enables communication between devices operating at different voltage levels. It utilizes a combination of MOSFETs and control circuitry to automatically sense the direction of data flow and adjust the voltage levels accordingly.

When the OE (Output Enable) pin is low, the translator is active, and the SDA and SCL signals are bidirectionally translated between the A-side and B-side voltage domains. The channel select inputs (A1, A2, B1, B2) determine the translation direction.

The device operates by using a reference voltage (VREF) to determine the logic thresholds for high and low levels. It supports various protocols such as I2C and SMBus, making it suitable for a wide range of applications.
