description/ordering information
These octal buffers and line drivers feature the
performance of the popular ’HC240 series and
offer 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
’HC540 devices provide inverted data at the
outputs.
