74LVC240ABQ: Octal buffer/line driver with 5 V tolerant inputs/outputs; inverting; 3-state
The 74LVC240A is an octal 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 of slower input rise and fall times.
Inputs can be driven from either 3.3 V or 5 V devices. When disabled, up to 5.5 V can be applied to the outputs. These features allow the use of these devices as translators in mixed 3.3 V or 5 V applications.
The 74LVC240A is functionally identical to the 74LVC244A except that the 244 has non-inverting outputs.
