Working Principles

The CLVC574AQDWRG4Q1 is a logic level converter that facilitates communication between devices operating at different voltage levels. It utilizes a bidirectional voltage translation technique to convert signals from one voltage domain to another. The device consists of four bidirectional channels, each capable of converting logic signals between two voltage domains.

The input/output pins (I/O) on side A are connected to the corresponding pins on side B through a level-shifting circuit. The direction of signal flow is controlled by the Output Enable (OE) pins. When OE is low, the device is enabled, allowing bidirectional signal transmission. Conversely, when OE is high, the device is disabled, isolating the input and output pins.

The CLVC574AQDWRG4Q1 operates by monitoring the voltage levels on both sides and translating them accordingly. It ensures that logic high levels on one side are correctly translated to the corresponding voltage level on the other side, and vice versa. This enables seamless communication between devices operating at different voltage levels.
