SN74LV541APW

Буфер / драйвер линии, неинвертирующий, 3 состояния, 2В до 5.5В, TSSOP-20.

The SN74LV541APW is an octal Buffer/Driver with 3-state outputs and is designed for 2 to 5.5V VCC operation. This device is ideal for driving bus lines or buffer memory address registers. It features inputs and outputs 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 input is high, all corresponding outputs are in the high-impedance state. The outputs provide non-inverted data when they are not in the high-impedance state. To ensure the high-impedance state during power up or power down, both 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 The SN74LV541A device is fully specified for partial-power-down applications using IOFF. The IOFF circuitry disables the outputs, preventing damaging current backflow through the devices when it is powered down.
