Overview
The SN74LVC541APWRE4, produced by Texas Instruments, is an octal buffer/driver designed for operation within a voltage range of 1.65 V to 3.6 V. This device is particularly suited for driving bus lines or buffering memory address registers. It features inputs and outputs on opposite sides of the package, which facilitates easier printed circuit board layout. The SN74LVC541APWRE4 is also capable of mixed-mode signal operation, allowing it to act as a translator in systems that use both 3.3-V and 5-V devices.
