description/ordering informationThese 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 ’ACT241 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.
ORDERING INFORMATION Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are
available at www.ti.com/sc/package.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
