Description

The SN54AHC540 octal buffers/drivers are ideal for driving bus lines or buffer memory address registers. SN54AHC540 features 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 VCC through a pullup resistor; the minimum value of the resistor SN54AHC540 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.
