description
This quadruple bus buffer gate is designed for 1.65-V to 3.6-V V
CC
operation.
The SN74LVC126A 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.
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 SN74LVC126A is characterized for operation from 鈥?0擄C to 85擄C.
