Working Principles

The 74ALVCF162835APAG is designed to translate logic levels between two different voltage domains. It utilizes a combination of CMOS technology and level-shifting circuitry to achieve bidirectional voltage translation. The inputs and outputs are protected against electrostatic discharge (ESD) to ensure reliable operation.

When an input signal from one voltage domain is applied to the corresponding channel input pins (A1-A16 or B1-B16), the IC translates the logic level to the voltage range compatible with the other domain. The translated signal is then available at the respective output pins.
