74LVC244A-Q100; 74LVCH244A-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.
