SN74LVC541ADBR

The SN74LVC541ADBR is an octal Buffer/Driver with 3-state outputs and designed for 1.65 to 3.6V VCC operation. The device features inputs and outputs 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. Inputs can be driven from either 3.3/5V devices. This feature allows the use of these devices as translators in a mixed 3.3/5V system environment. This device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.
