Working Principles

The SN74CB3T3125PW utilizes CMOS technology to achieve bidirectional voltage level shifting. It consists of four independent level shifters that can be controlled by the OE (Output Enable) pin. When OE is low, the device is enabled, allowing the translation of logic levels between the input and output pins. When OE is high, the device is disabled, isolating the input and output pins.
