3 Description

The SN74LVC2G125 device is a dual bus buffer

gate, designed for 1.65-V to 5.5-V VCC operation.

This device features dual line drivers with 3-state

outputs. The outputs are disabled when the

associated output-enable (OE) input is high.

NanoFree™ package technology is a major

breakthrough in IC packaging concepts, using the die

as the package.

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.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow

through the device when it is powered down.
