– 1000-V Charged-Device Model (C101)

This octal buffer/line driver is designed for 1.65-V to 3.6-V V

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- Ω resistors to reduce overshoot and

undershoot.

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.
