SN74LV125A-Q1 - Automotve Catalog Quadruple Bus Buffer Gates With 3-State Outputs

The SN74LV125A-Q1 quadruple bus buffer gate is designed for 2-V to 5.5-V V_CC operation.

This device 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_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

These devices are fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the devices when they are powered down.
