This octal buffer/line driver is designed for 1.65-V to 3.6-V VCC operaTIon.
The SN74LVC2244A is organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.
The outputs, which are designed to sink up to 12 mA, include equivalent 26- resistors to reduce overshoot and undershoot.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in a mixed 3.3-V/5-V system environment.
This device is fully specified for parTIal-power-down applicaTIons using Ioff. The Ioff circuitry disables the outputs, prevenTIng damaging current backflow through the device when it is powered down.
