description  
This quadruple bus buffer gate is designed for 1.65-V to 3.6-V V  
operation.  
CC  
The SN74LVC125A 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 V through a pullup  
CC  
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 these devices as translators  
in a mixed 3.3-V/5-V system environment.  
The SN74LVC125A is characterized for operation from –40°C to 85°C.
