Description
These 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 ’HC 244 devices are organized as two 4-bit buffers/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 high-impedance state.
