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.

1 20 19

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.

9 10 11 12 13

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.

The SN54AHC540 is characterized for operation over the full military temperature range of –55°C to 125°C.

The SN74AHC540 is characterized for operation from –40°C to 85°C.
