This quadruple bus buffer gate is designed for 1.65-V to 3.6-V VCC operation.
The SN74LVC125AQDRG4Q1 device features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is high.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment.
