Working Principles

The SN64BCT25244DWG4 utilizes a combination of MOSFETs and level-shifting circuitry to achieve bidirectional voltage translation. When an input signal is received on one channel (A Port), the circuitry translates it to the corresponding voltage level on the other channel (B Port) and vice versa. The output enable control allows the user to enable or disable the translation process as needed.
