SN74HC164NE4

The SN74HC164NE4 is an integrated circuit (IC) from Texas Instruments, specifically designed as an 8-bit serial-in, parallel-out shift register. It belongs to the 74HC (High-speed CMOS) family, which is known for its high-speed operation and low power consumption. Here’s a detailed description of its features and specifications:

General Features:

• Type: 8-bit Shift Register
• Functionality: The SN74HC164NE4 takes in serial data and shifts it through a series of flip-flops, allowing for the parallel output of the stored data.
• Data Input: It has a single data input (DS) where serial data is fed into the register.
• Clock Input: The device features a clock input (CLK) that controls the timing of the data shifting process. On each rising edge of the clock signal, the data present at the DS input is shifted into the first flip-flop, and the existing data is shifted to the next flip-flop in the series.
• Output: It provides eight parallel outputs (Q0 to Q7), which can be used to drive other digital circuits or devices.

Electrical Characteristics:

• Supply Voltage (Vcc): Typically operates at a supply voltage range of 2V to 6V, making it compatible with various logic levels.
• Input Voltage Levels: The input high voltage (VIH) and input low voltage (VIL) levels are defined to ensure proper logic level recognition.
• Output Drive Capability: The outputs can drive standard TTL loads, making it suitable for interfacing with other digital components.

Package Information:

• Package Type: The SN74HC164NE4 is available in various package types, including DIP (Dual In-line Package) and SOIC (Small Outline Integrated Circuit), which allows for flexibility in PCB design and assembly.
• Pin Configuration: The IC typically has 16 pins, with specific pins designated for power supply, ground, clock input, data input, and the eight output pins.

Applications:

• Data Storage: Used in applications where data needs to be temporarily stored and then accessed in parallel.
• LED Control: Commonly used in LED driving applications, where serial data can control multiple LEDs with fewer pins.
• Data Communication: Useful in communication systems where data needs to be shifted and processed serially before being output in parallel.

Performance:

• Speed: The SN74HC164NE4 is capable of high-speed operation, with typical propagation delays in the nanosecond range, making it suitable for fast digital circuits.
• Power Consumption: As a CMOS device, it exhibits low static power consumption, which is advantageous for battery-operated devices.

Summary:

The SN74HC164NE4 is a versatile and efficient 8-bit shift register that is widely used in digital electronics for data manipulation and control. Its combination of high-speed performance, low power consumption, and ease of integration makes it a popular choice for engineers and designers in various applications.
