The ’AHCT541 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 2-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 non-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 VCC through a pullup resistor; the minimum
value of the resistor is determined by the current-sinking capability of the driver.
