description
The SN74ABT541B octal buffer and line driver is ideal for driving bus lines or buffering memory address
registers. 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 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 V_CC 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 V_CC through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
