description/ordering information

This octal buffer and line driver is designed specifically for low-voltage (3.3-V) V

operation, but with the

The SN74LVT240A is organized as two 4-bit buffer/line drivers with separate output-enable (OE) inputs. When

OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the

high-impedance state.

When V

is between 0 and 1.5 V, the device is in the high-impedance state during power up or power down.

However, to ensure the high-impedance state above 1.5 V, OE should be tied to V

the minimum value of the resistor is determined by the current-sinking capability of the driver.

This device is fully specified for hot-insertion applications using I and power-up 3-state. The I circuitry

disables the outputs, preventing damaging current backflow through the device 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.
