SN74LV164APW

The SN74LV164APW is an integrated circuit (IC) from Texas Instruments, specifically designed as an 8-bit serial-in, parallel-out shift register. This device is part of the LV (Low Voltage) logic family, which allows it to operate at lower supply voltages while maintaining high-speed performance and low power consumption.

Key Features:

1. Functionality: The SN74LV164APW takes in serial data and shifts it through a series of flip-flops, allowing for the storage and parallel output of 8 bits of data. This makes it ideal for applications where data needs to be shifted in and then accessed in parallel.

2. Operating Voltage: The device operates over a wide voltage range, typically from 2.0V to 5.5V, making it suitable for various low-voltage applications.

3. Speed: The SN74LV164APW can operate at high speeds, with a maximum clock frequency of up to 30 MHz at 5V, ensuring quick data processing and transfer.

4. Output Configuration: The outputs are designed to be high-impedance, allowing for easy interfacing with other digital circuits without loading them down.

5. Pin Configuration: The IC is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) or other package types, making it compact and suitable for space-constrained applications. The pins include inputs for serial data, a clock input, a reset input, and parallel outputs.

6. Reset Functionality: The device features an asynchronous reset that can clear the shift register, setting all outputs to a low state, which is useful for initializing the device.

7. Temperature Range: The SN74LV164APW is rated for operation over a temperature range of -40°C to +125°C, making it suitable for industrial and automotive applications.

8. Applications: Common applications include data storage, digital signal processing, LED control, and interfacing with microcontrollers or other digital systems.

Electrical Characteristics:

• Input High Voltage (VIH): Typically around 2.0V to 5.5V, depending on the supply voltage.
• Input Low Voltage (VIL): Typically around 0V to 0.8V.
• Output High Voltage (VOH): Close to the supply voltage when the output is high.
• Output Low Voltage (VOL): Typically around 0V when the output is low.

Summary:

The SN74LV164APW is a versatile and efficient 8-bit shift register that provides a reliable solution for serial-to-parallel data conversion in low-voltage applications. Its combination of speed, low power consumption, and robust performance makes it a popular choice among engineers and designers in various electronic projects.
