74LV244A

Octal buffer/line driver; 3-state

The 74LV244A is an 8-bit buffer/line driver with 3-state outputs. The device features two output enables (1OE and 2OE). A HIGH on nOE causes the associated outputs to assume a high-impedance OFF-state.

Inputs are overvoltage tolerant. This feature allows the use of these devices as translators in mixed voltage environments.

Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times.

This device is fully specified for partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
