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.

The –1 versions of SN74ALS540 and SN74ALS541 are identical to the standard versions, except that the recommended maximum IOL is increased to 48 mA. There is no –1 version of the SN54ALS541.
