MM74HC243N Description

Short technical summary and product information.

The MM74HC243N is a high-speed CMOS logic buffer from National Semiconductor. This device functions as a non-inverting buffer, providing a reliable interface for digital signals. It is designed to operate within a wide supply voltage range of 2V to 6V, making it suitable for various applications.

 

The buffer features two independent elements, each capable of handling four bits. This configuration allows for efficient signal buffering and distribution within complex circuits. The MM74HC243N is packaged in a standard 20-DIP (Dual In-line Package) format, designed for through-hole mounting, which simplifies integration into printed circuit boards.

 

With its robust design and adherence to the 74HC series standards, the MM74HC243N is a dependable choice for applications requiring signal buffering and level shifting. Its non-inverting nature ensures that the output signal directly corresponds to the input signal, maintaining signal integrity.
