description
'ABT540 octal buffers line drivers ideal driving lines buffer memory address registers. devices feature inputs outputs opposite sides package that facilitate printed circuit board layout. 3-state control gate 2-input gate with active-low inputs that either output-enable (OE1 OE2) input high, corresponding outputs high-impedance state.
ensure high-impedance state during power power down, should tied through pullup resistor; minimum value resistor determined current-sinking capability driver. SN54ABT540 characterized operation over full military temperature range -55°C 125°C. SN74ABT540 characterized operation from -40°C 85°C.
