Working Principles

The SN74ALVCH162827VR is a voltage-level translator that operates by converting signals between different voltage domains. It uses a combination of MOSFETs and CMOS technology to achieve bidirectional translation. The direction of translation is controlled by the OE# pin, which determines whether the device is in the active or high-impedance state.

When the OE# pin is low, the device is active, and the input signals are translated to the corresponding output voltage level. When the OE# pin is high, the device enters a high-impedance state, disconnecting the input and output pins.
