1 / 20 page SN54AHC240, SN74AHC240 OCTAL BUFFERS/DRIVERS WITH 3-STATE OUTPUTS SCLS251H – OCTOBER 1995 – REVISED JULY 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Operating Range 2-V to 5.5-V VCC D Latch-Up Performance Exceeds 250 mA Per JESD 17 description/ordering information These octal buffers/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 ’AHC240 devices are organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, 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; the minimum value of the resistor is determined by the current-sinking capability of the driver.
