Texas Instruments SN74HC540PWR

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.
