description/ordering information
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 ’HC241
devices are organized as two 4-bit buffers/drivers with separate output-enable (1OE and 2OE) inputs. When
1OE is low or 2OE is high, the device passes noninverted data from the A inputs to the Y outputs. When 1OE
is high or 2OE is low, the outputs for the respective buffers/drivers are in the high-impedance state.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51-7.
