SN74AC244DWG4
Buffer/Line Driver 8CH Non-Inverting 3-ST CMOS 20Pin SOIC Tube
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 ’AC244 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.
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.
• 2-V to 6-V VCC Operation
• Inputs Accept Voltages to 6 V
• Max tpd of 7.5 ns at 5 V
