Overview
The SN74LV541ADWR is an octal buffer/driver device manufactured by Texas Instruments. This component is designed to operate within a voltage range of 2-V to 5.5-V VCC, making it versatile for various applications. It features 3-state outputs, which allow the outputs to be in a high-impedance state when not in use. The device is ideal for driving bus lines or buffering memory address registers due to its ability to handle mixed-mode voltage operation on all ports.
The SN74LV541ADWR is packaged in a 20-pin SOIC (DW) package, facilitating easy integration into surface-mount designs. It supports partial-power-down mode operation through its Ioff circuitry, preventing damaging current backflow when the device is powered down.
