On All Other Products, Production Processing Does Not Necessarily Include Testing of All Parameters. 2 Applications - Servers - LED Displays - Network Switches - Tele Infrastructure - Motor Drivers - I/O Expanders 1OE 1 3 Description The SNx4HC244 octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SNx4HC244 devices are organized as two 4bit buffers and drivers with separate output-enable (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.
