74LVC244ADB-Q100: Octal buffer/line driver; 3-state
The 74LVC244A-Q100; 74LVCH244A-Q100 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-Q100 bus hold on data inputs eliminates the need for external pull-up
resistors to hold unused inputs.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
