description/ordering information
These octal buffers and line drivers are designed
specifically to improve the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters.
The ’AC241 devices are organized as two 4-bit
buffers/drivers with separate complementary
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 are in the high-impedance state.
To ensure the high-impedance state during power
up or power down, OE should be tied to VCC
through a pullup resistor and OE should be tied to
GND through a pulldown resistor; the minimum
value of the resistor is determined by the
current-sinking or the current-sourcing capability
of the driver.

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.
