This device is part of the 74HC family, which is known for its high-speed operation and low power consumption. Below is a detailed description of its features, specifications, and applications:

General Description:

The 74HC4094 is an 8-bit serial-in, parallel-out shift register. It is designed to convert serial data into parallel data, making it useful for applications where data needs to be processed in a parallel format after being received in a serial format. The device can be used in various digital applications, including data storage, data transfer, and signal processing.

Key Features:

• 8-Bit Shift Register: The device can store and shift 8 bits of data.
• Serial Input: Data can be entered into the register serially, one bit at a time.
• Parallel Output: The stored data can be accessed in parallel, allowing for simultaneous reading of all bits.
• Clock Input: The shift operation is synchronized with a clock signal, ensuring that data is shifted in a controlled manner.
• Asynchronous Reset: The device includes a reset function that can clear the register asynchronously, setting all outputs to a low state.
• High-Speed Operation: The 74HC series is capable of operating at high speeds, making it suitable for fast data processing applications.
• Low Power Consumption: The CMOS technology used in this device allows for low static power consumption, which is beneficial for battery-operated devices.

Electrical Characteristics:

• Supply Voltage (Vcc): Typically operates at 2V to 6V, making it compatible with a wide range of digital circuits.
• Input Voltage Levels: Compatible with standard TTL (Transistor-Transistor Logic) levels, ensuring interoperability with other logic families.
• Output Drive Capability: Can drive standard TTL loads, making it suitable for interfacing with other digital components.

Pin Configuration:

The 74HC4094D,653 typically comes in a 16-pin dual in-line package (DIP) or surface-mount package (SOIC). The pin configuration includes:

• Serial Data Input (DS): The input pin for serial data.
• Clock Input (SHCP): The clock signal input for shifting data.
• Latch Clock Input (STCP): Used to transfer the shifted data to the output registers.
• Reset (MR): An active-low reset pin to clear the register.
• Parallel Outputs (Q0 to Q7): Eight output pins for accessing the stored data in parallel.

Applications:

• Data Communication: Used in applications where data needs to be transmitted serially and received in parallel.
• Microcontroller Interfacing: Commonly used to expand the number of output pins available from a microcontroller.
• LED Control: Can be used to control multiple LEDs by shifting data to turn them on or off in a specific sequence.
• Data Storage: Useful in temporary data storage applications where data needs to be shifted in and out.

Conclusion:

The 74HC4094D,653 from Nexperia is a versatile and efficient shift register that provides a reliable solution for serial-to-parallel data conversion. Its combination of high-speed operation, low power consumption, and ease of use makes it an ideal choice for a wide range of digital applications. Whether used in consumer electronics, industrial automation, or communication systems, this device is a valuable component for engineers and designers.
