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.
● 3-State Outputs Drive Bus Lines or Buffer Memory Address Registers
● pnp Inputs Reduce dc Loading
● Data Flowthrough Pinout (All Inputs on Opposite Side From Outputs)
