Buffers, Drivers, Receivers, Transceivers FAQ

Can the SN74LVC125ADRE4 translate signals from 5V to 3.3V?

Yes, the inputs accept voltages up to 5.5V, allowing the device to function as a translator in mixed 3.3V/5V system environments.

How are the outputs disabled?

Each output is disabled when its associated output-enable (OE) input is high. To ensure a high-impedance state during power-up or power-down, OE should be tied to VCC through a pullup resistor.
