74HC165BQ,115

The 74HC165BQ,115 is an 8-bit parallel-in/serial-out shift register from Nexperia, designed for high-speed digital applications. It is part of the 74HC family, which is known for its high-speed CMOS technology, making it suitable for a wide range of electronic circuits.

Key Features:

1. Functionality: The 74HC165 is capable of capturing 8 bits of parallel data and shifting it out serially. This makes it ideal for applications where multiple bits of data need to be transmitted over a single line, such as in microcontroller interfacing.

2. Parallel Input: The device has 8 parallel data inputs (D0 to D7) that allow for simultaneous data loading. This feature is particularly useful for reading multiple digital signals at once.

3. Serial Output: The output is provided in a serial format, which can be easily interfaced with microcontrollers or other digital devices that require serial data input.

4. Clock Input: The shift register is controlled by a clock input (CLK), which determines when the data is shifted. Each clock pulse shifts the data one position to the right, allowing for the serial output to be read.

5. Load Control: The device includes a Load (PL) control pin that allows the user to load the parallel data into the register. When this pin is activated, the data present at the parallel inputs is captured and stored in the register.

6. Reset Functionality: The 74HC165 also features a Reset (SR) pin that can be used to clear the register, setting all outputs to a low state.

7. High-Speed Operation: The device operates at high speeds, with a maximum clock frequency of up to 30 MHz, making it suitable for fast data processing applications.

8. Voltage Range: It operates over a wide voltage range, typically from 2V to 6V, allowing for compatibility with various logic levels.

9. Package Type: The 74HC165BQ,115 is available in a TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications.

10. Power Consumption: Being a CMOS device, it has low power consumption, which is advantageous for battery-operated devices.

Applications:

• Microcontroller Interfacing: Ideal for expanding the number of input/output pins on microcontrollers.
• Data Acquisition Systems: Useful in systems that require the collection of multiple digital signals.
• LED Control: Can be used to control multiple LEDs with fewer microcontroller pins.
• Sensor Data Reading: Suitable for reading data from multiple sensors in a compact manner.

Electrical Characteristics:

• Input Voltage Levels: Compatible with standard TTL logic levels.
• Output Drive Capability: Can drive standard TTL loads, making it versatile for various applications.

In summary, the 74HC165BQ,115 from Nexperia is a versatile and efficient 8-bit shift register that provides a simple solution for parallel-to-serial data conversion, making it a valuable component in many digital electronic designs.
