SN74AHC541-Q1

SN74AHC541ĆQ1 OCTAL BUFFER/DRIVER WITH 3ĆSTATE OUTPUTS SCLS603A − DECEMBER 2004 − REVISED APRIL 2008 D Qualified for Automotive Applications D Operating Range 2-V to 5.5-V VCC D Latch-Up Performance Exceeds 250 mA Per JESD 17 description/ordering information The SN74AHC541 octal buffer/driver is ideal for driving bus lines or buffer memory address registers. This device features inputs and outputs on opposite sides of the package to facilitate printed circuit board layout.

The outputs provide noninverted data when they are not 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.
