The MM74HC595M is an integrated circuit (IC) component that belongs to the 74HC family of high-speed CMOS logic devices. It is a shift register with a storage register and a 3-state output stage. With a wide range of applications in digital electronics, the MM74HC595M offers several key features that make it versatile and useful in various circuit designs.
1. Shift Register: The MM74HC595M incorporates an 8-bit shift register that allows serial input of data. The data input is shifted through the register with each clock pulse, providing flexible data manipulation.
2. Storage Register: Along with the shift register, this IC component also features an 8-bit storage register. Once the desired data is shifted into the storage register, it is held and can be latched onto the output pins when required.
3. Serial Input and Output Pins: The MM74HC595M comes with two serial input pins, SER (serial data input) and SRCLK (shift register clock input). These pins allow the user to serially input data into the shift register. Additionally, it has an SRCLR (shift register clear) input pin that clears the shift register and storage register asynchronously. The serial output pin, QH', allows daisy-chaining multiple devices for cascading
