The device features inputs and outputs on opposite sides of the package to 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 eight outputs are in the high-impedance state. The outputs are in a high-impedance state during power up and power down while the supply voltage is less than approximately 3 V. The SN64BCT541A is characterized for operation from − 40°C to 85°C and from 0°C to 70°C.
