DESCRIPTION/ORDERING INFORMATION
The SN74LVC2G125-Q1 is a dual bus buffer gate designed for 1.65-V to 5.5-V V
CC
operation. This device
features dual line drivers with 3-state outputs. The outputs are 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
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
This device is fully specified for partial-power-down applications using I
off
. The I
off
circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
