description/ordering information

The ’AHC541 octal buffers/drivers are ideal for

driving bus lines or buffer memory address

registers. These devices feature inputs and

outputs on opposite sides of the package to

facilitate printed circuit board layout.

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 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.
