The DM74ALS165M is an integrated circuit (IC) component that belongs to the 74ALS family, a type of high-speed bipolar digital logic ICs. This specific IC is a parallel-to-serial shift register, which means it is designed to convert data from parallel format to serial format. Here, we will provide an overview and key features of the DM74ALS165M.
The DM74ALS165M features a 16-bit parallel input and a single-bit serial output. It operates on a wide supply voltage range of 4.5V to 5.5V, making it compatible with various digital systems. With its ALS (Advanced Low-power Schottky) technology, this IC provides a high-speed operation while maintaining low power consumption.
One of the primary functions of the DM74ALS165M is to convert parallel data to serial data with the use of a shifting clock signal. It stores the incoming data on its 16 parallel inputs (commonly labeled as D0-D15) and shifts it out sequentially through its single serial output (referred to as Q output). The serial output follows the rising or falling edge of the clock signal, depending on the IC version (specified by a letter at the end, e.g., DM74ALS165N).
This IC component also offers additional features that enhance its versatility and compatibility with different applications. These include:
