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.
GND
The 3-state control gate is a two-input AND gate with active-low inputs so that if either output-enable (OE1 or
OE2) input is high, all corresponding outputs are in the high-impedance state. 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 V through a pullup
CC
resistor; the minimum value of the resistor is determined by the current-sinking 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.
