Overview
The SN74LVC541APW is an octal buffer/driver produced by Texas Instruments, designed for operation within a voltage range of 1.65 V to 3.6 V. This device is ideal for driving bus lines or buffering memory address registers. It features inputs and outputs on opposite sides of the package, facilitating easier printed circuit board layout. The SN74LVC541APW is also capable of mixed-mode signal operation, allowing it to act as a translator in systems with both 3.3-V and 5-V components.
