description
This quadruple bus buffer gate is designed for 1.65-V to 3.6-V V_CC operation.
The SN74ALVC126 features independent line drivers with 3-state outputs. Each output is disabled when the
associated output-enable (OE) input is low.
To ensure the high-impedance state during power up or power down, OE should be tied to GND through a
pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of
the driver.
The SN74ALVC126 is characterized for operation from –40°C to 85°C.
