Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle hot insertion?

The SN74LVCZ16245ADGG includes Ioff circuitry and power-up 3-state functionality. This ensures outputs are disabled during power-down to prevent backflow and placed in a high-impedance state during power-up to avoid driver conflicts.

Can this transceiver interface 5-V logic with 3.3-V logic?

Yes, it supports mixed-mode signal operation. Inputs can accept voltages up to 5.5 V, allowing it to translate signals between 5-V and 3.3-V devices while operating from a 2.7-V to 3.6-V supply.
