description/ordering information

The ’AHC540 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 inverted 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.
