The DS9638CN is an integrated circuit (IC) component designed to provide a complete serial interface for parallel buses. It is commonly used in computer systems and other electronic devices for data communication between parallel devices. The IC is manufactured by Maxim Integrated, a renowned semiconductor company.
Key Features:
1. Parallel-to-Serial Interface: The DS9638CN allows easy conversion of parallel bus data to a serial format. It is capable of handling up to eight parallel inputs, making it suitable for various applications that require serial communication.
2. Input/Output Voltage Levels: This IC supports both TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) voltage levels for its input and output pins. It operates with a typical voltage range of 2V to 6V, facilitating compatibility with a wide range of devices.
3. Shift Register and Frame Counter: The DS9638CN incorporates a shift register and a frame counter. The shift register enables sequential transmission of data from the parallel inputs to the serial output. The frame counter provides synchronization for framing the transmitted data.
4. Synchronous or Asynchronous Operation: This IC supports both synchronous and asynchronous modes of operation. In synchronous mode, the shift register is clocked using an external clock signal, ensuring precise timing and control. Asynchronous mode allows flexible data transmission without the need for an external clock
