These octal buffers and line drivers are designed to have the performance
of the popular SN54LS240/SN74LS240 series and, at the same time, offer a pinout
having the inputs and outputs on opposite sides of the package. This arrangement
greatly enhances printed circuit board layout.
The three-state control gate is a 2-input NOR such that if either G1\ or G2\ are high, all eight outputs are in the high-impedance
The 'LS540 offers inverting data and the 'LS541 offers true data at the
The SN54LS540 and SN54LS541 are characterized for operation over the full
