Working Principles

The SN74ACT533PW is a logic level translator that enables communication between two different voltage domains. It uses a combination of MOSFETs and CMOS technology to achieve bidirectional data flow. The device operates by monitoring the input voltage levels and translating them to the corresponding output voltage levels based on the specified supply voltage range.

When the output enable (OE) pin is low, the device is enabled, and the input signals are translated to the output signals. When the OE pin is high, the device is disabled, and the outputs are in a high-impedance state.
