3 Description

These octal buffers and line drivers are designed

specifically to improve both the performance

and density of 3-state memory address drivers,

clockdrivers, and bus-oriented receivers and

transmitters. The SNx4HCT244 devices are organized

as two 4-bit buffers or drivers with separate outputenable

(OE) inputs. When OE is low, the device

passes noninverted data from the A inputs to the Y

outputs. When OE is high, the outputs are in the highimpedance

state.
