SN54ABT540 OCTAL BUFFERS/DRIVERS

The ’ABT540 octal buffers and line drivers are ideal for driving bus lines or buffer memory address registers. The devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board layout. The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1 or OE2) input is high, .

Features

l buffers and line drivers are ideal for driving bus lines or buffer memory address registers. The devices feature inputs and outputs on opposite sides of the package that facilitate printed circuit board layout. The 3-state control gate is a 2-input AND gate with active-low inputs so that if either output-enable (OE1 or OE2) input is high, all corresponding outputs are in the high-impedance state.
