The SN74ALS165D is an integrated circuit (IC) component that belongs to the SN74ALS family of parallel-in/serial-out shift registers. It is a 8-bit synchronous serial shift register that can be used for a variety of applications, such as data storage, multiplication, division, and serial-to-parallel conversion.
One of the key features of the SN74ALS165D is its compatibility with both CMOS and TTL voltage levels. This makes it versatile and allows it to be easily integrated into existing systems with different voltage requirements.
Another important feature is its 8-bit parallel input, which enables the user to load data into the shift register in parallel. This can be done through individual input pins or by cascading multiple SN74ALS165D chips together to achieve a larger data storage capacity.
The SN74ALS165D also supports serial data input and output, allowing for easy communication with other devices using a common clock signal. It features a synchronous design, meaning that the data is loaded into the register and shifted out simultaneously with the clock pulses.
Furthermore, this IC component offers two control inputs: clock (CLK) and clear (CLR). The clock input controls the timing of the data shift, while the clear input resets the register to a known state if required
