SN54ABT541 SN74ABT541B octal buffers line drivers ideal driving lines buffering memory address registers. devices feature inputs outputs opposite sides package facilitate printed circuit board layout. 3-state control gate two-input gate with active-low inputs that either output-enable (OE1 OE2) input high, eight outputs high-impedance state.
description
When between device high-impedance state during power power down. However, ensure high-impedance state above should tied through pullup resistor; minimum value resistor determined current-sinking capability driver. SN54ABT541 characterized operation over full military temperature range -55°C 125°C. SN74ABT541B characterized operation from -40°C 85°C.
