Working Principles

The 74LVC162244ADL,118 is designed to shift voltage levels between different logic families. It utilizes a combination of CMOS technology and tri-state outputs to achieve bidirectional voltage translation. The inputs and outputs are protected against electrostatic discharge (ESD) and excessive current.

When the output enable (OE) pin is active, the device allows data transmission in both directions. When the OE pin is inactive, the outputs are in a high-impedance state, effectively disconnecting the device from the bus.

The IC operates within a specified supply voltage range and provides fast propagation delay for efficient data transfer. It is essential to ensure compatibility between input and output voltage levels to prevent damage to the device.
