SN74ABT125D

The SN74ABT125D is a quadruple bus Buffer Gate features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE)\ input is high. This device is fully specified for hot-insertion applications using IOFF and power-up 3-state. The IOFF circuitry disables the outputs, preventing damaging current backflow through the devices when it is powered down. The power-up 3-state circuitry places the outputs in the high-impedance state during power up and power down, which prevents driver conflict. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pull-up resistor, the minimum value of the resistor is determined by the current-sinking capability of the driver.

• High-drive outputs
• IOFF and power-up 3-state support hot insertion
• Latch-up performance exceeds 500mA per JEDEC standard JESD-17
• <lt/>1V at VCC = 5V, TA = 25°C VOLP (output ground bounce)
• Green product and no Sb/Br
