• HV3418PG-G Logic - Shift Registers
1. Application Field

The HV3418PG-G is a versatile logic shift register that can be used to store digital data in a chain of non-volatile memory. Specifically, the HV3418PG-G is used to extend the length of a logic signal, or to buffer large numbers of logic states. The register is programmable, allowing it to be customized to the needs and logic flow of individual applications.

Applications for the HV3418PG-G include reliable memory for communications systems, data logging, and digital control. In communications applications, the register can be used to store digital data from a variety of sources including Serial Peripheral Interface (SPI), General Purpose Parallel (GPP), Inter-Integrated Circuit (I2C), Universal Asynchronous Receiver Transmitter (UART), and even analogue signals. The register can also be used to store data from industrial sensors and control systems, like temperature and flow rate readings. Finally, due to its extended memory length and programmable design, the HV3418PG-G is often used in the manufacture of automotive electronics, computers, and data storage devices.

2. Working Principle

The HV3418PG-G utilizes a cascaded architecture to expand its logic input to larger lengths. A row of latches is used to store consecutive bits of data, with each latch accepting a 0 or 1 at its input notch. Reading data from the register is achieved through a multiplexer which selects between both sides of the latched data, and then generates a serial stream of the multiplexed output. This multiplexer has the flexibility to be set at either the low or high bit order.

The programmable design of the HV3418PG-G allows it to be tailored to the application needs of different users. The register can be remotely programmed with custom settings, such as clock divider, start sequence, and various reset options. The gain and hysteresis of the logic signal can also be adjusted with a digital potentiometer, allowing users to fine-tune the output signal. These programmable settings make the HV3418PG-G a valuable asset for applications where reliable and precise digital data storage and manipulation is required.

The HV3418PG-G is a highly configurable logic shift register with a myriad of application uses. Its programmable settings, long memory length, and serial multiplexer make it an excellent choice for digitally recording, organizing, and routing data. This chip is now a standard component in digital logic and communication systems, making it a valuable piece of hardware to own.
