74LVC244A; 74LVCH244A Octal buffer/line driver; 3-state Rev. 8 26 June 2013 Product data sheet 1. General description The 74LVC244A; 74LVCH244A is an octal non-inverting buffer/line driver with 3-state outputs. The 3-state outputs are controlled by the output enable inputs 1OE and 2OE. A HIGH on nOE causes the outputs to assume a high-impedance OFF-state. Schmitt-trigger action at all inputs makes the circuit highly tolerant for slower input rise and fall times. Inputs can be driven from either 3.3 V or 5.0 V devices. In 3-state operation, outputs can handle 5 V. These features allow the use of these devices as translators in a mixed 3.3 V and 5 V environment. The 74LVCH244A bus hold on data inputs eliminates the need for external pull-up resistors to hold unused inputs. 2. Features [ ... ]
