74LV244A Octal buffer/line driver 3-state Rev. 1 23 November 2016 Product data sheet 1. General description 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 I . The I OFF OFF circuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down. 2.
