产品概述
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
state.
The 'LS540 offers inverting data and the 'LS541 offers true data at the
outputs.
The SN54LS540 and SN54LS541 are characterized for operation over the full
military temperature range of -55°C to 125°C. The SN74LS540 and SN74LS541
are characterized for operation from 0°C to 70°C.
