The devices feature inputs and outputs on opposite sides of the package to facilitate printed circuit board layout. The 3-state control gate is a two-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. When VCC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The SN54ABT541 is characterized for operation over the full military temperature range of –55 °C to 125°C. The SN74ABT541B is characterized for operation from –40 °C to 85°C.
