TI SN74HC540 8-Bit Buffer Line Driver HC 3-State Inv 2 to 6V SOIC20 (Pk of 2)

Manufactured by Texas Instruments - SOIC20 SMD Package

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.
