FK PACKAGE (TOP VIEW) A2 A1 OE1 VCC description The 'LV541A devices are octal buffers/drivers designed for 2-V to 5.5-V VCC operation. These devices are ideal for driving bus lines or buffer memory address registers. They feature inputs and outputs on opposite sides of the package to facilitate printed circuit board layout.

The outputs provide noninverted data when they are not in the high-impedance state. To ensure the high-impedance state during power up or power down, 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 SN54LV541A is characterized for operation over the full military temperature range of -55C to 125C. The SN74LV541A is characterized for operation from -40C to 85C.
