– 200-V Machine Model (A115-A)

– 1000-V Charged-Device Model (C101)

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.
