description/ordering informationThese octal buffers and line drivers are designed to have the performance of the ’HCT240 devices and a pinout
with inputs and outputs on opposite sides of the package. This arrangement greatly facilitates printed circuit
board layout.
The 3-state control gate is a 2-input NOR. If either output-enable (OE1 or OE2) input is high, all eight outputs
are in the high-impedance state. The ’HCT540 devices provide inverted data at the outputs.
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.
