The 74LVC244A and 74LVCH244A are 8-bit buffer/line drivers with three state outputs. The devices can operate as two 4-bit buffers or one 8-bit buffer. Both devices have two output enables (1OE and 2OE), with each controlling four of the three-state outputs. A HIGH on nOE switches the outputs to a high-impedance OFF state. Inputs can be powered by either 3.3 or 5 V devices. This functionality enables these devices to function as translators in situations with both 3.3 V and 5 V. Schmitt-trigger activity at all inputs allows the circuit to tolerate slower input rise and fall times. This device is completely described for partial power down applications that use IOFF. The IOFF circuitry stops the output, preventing potentially harmful backflow current through the device when it is turned off.
