SN74LVC2G125DCTR

The SN74LVC2G125DCTR is a dual Bus Buffer Gate with 3-state outputs. The dual bus buffer gate designed for 1.65 to 5.5V VCC operation. 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 VCC through a pull-up 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. It is suitable for cable modem termination systems, power line communication modems, video broadcasting and infrastructure.

Advertencias

Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
