The IC component DM74LS165MX is a 8-bit shift register with parallel inputs and outputs manufactured by Fairchild Semiconductor. This device is commonly used in digital circuits to convert serial data into parallel data. Now, let's delve into the key features and an overview of this IC component:
1. Shift Register: The DM74LS165MX is designed as an 8-bit serial-in, parallel-out shift register. It allows the user to input data serially, with the capability of shifting the data to the right.
2. Parallel Outputs: It provides parallel outputs for all 8 bits of data. The output latches are transparent during the shifting process, enabling the parallel loading of data while simultaneously shifting the previous data.
3. Serial Data Input: The IC component features a single serial data input (DS) pin, which accepts the incoming data that needs to be shifted and converted to parallel format.
4. Data Clock: To control the shifting process, it requires a clock signal (Clock, CLK) input. The clock pulses are used to synchronize the shifting and parallel loading of data.
5. Serial Input Overflow: DM74LS165MX includes a serial input overflow (SI/O) terminal. When this pin is connected to the ground, the input data shifts in continuously. However, connecting SI/O to VCC allows data to be entered only after the entire 8-bit shift register is empty
