Working Principles

The SN74ABT861NSRE4 is a logic level translator that operates by converting signals between different voltage domains. It utilizes a combination of MOSFETs and CMOS technology to achieve bidirectional translation. The device consists of multiple channels, each capable of translating a pair of input signals to the corresponding output signals.

When the output enable (OE) pin is high, the translator is active, and the input signals are translated to the output signals based on the specified voltage levels. When the OE pin is low, the translator is disabled, and the output signals are in a high-impedance state.
