74LVC244A; 74LVCH244A Octal buffer/line driver; 3-state Rev. 9 — 13 August 2 018 Product data sheet 1. General des cription The 74LVC244A; 74LVCH244A is a n octal non-inverting buffer/line drive r with 3-state outputs. The 3-state out puts are controlled by the output enabl e inputs 1OE and 2OE. A HIGH on nOE cau ses the outputs to assume a high-impeda nce OFF-state. Schmitt-trigger action a t all inputs makes the circuit highly t olerant for slower input rise and fall times. Inputs can be driven from either 3.3 V or 5.0 V devices. In 3-state ope ration, outputs can handle 5 V. These f eatures allow the use of these devices as translators in a mixed 3
