Description
General part information
SN74ALS540-1 Series
These octal buffers and line drivers are designed to have the performance of the popular SN54ALS240A/ SN74ALS240A series and, at the same time, 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 gate such that, if either output-enable (OE1\ or OE2\) input is high, all eight outputs are in the high-impedance state.
The SN74ALS540 provides inverted data. The ’ALS541 provide true data at the outputs.
