SN74LV166APWR

The SN74LV166APWR is a high-speed, low-voltage, 8-bit shift register manufactured by Texas Instruments. It is designed for use in various digital applications, including data storage, data transfer, and signal processing. Below is a detailed description of its features and specifications:

General Features:

• Type: 8-bit Shift Register
• Technology: Low-Voltage CMOS (Complementary Metal-Oxide-Semiconductor)
• Package Type: TSSOP (Thin Shrink Small Outline Package)
• Pin Count: 16 pins
• Operating Voltage: Typically operates at a supply voltage range of 2.0V to 5.5V, making it suitable for low-power applications.

Functional Characteristics:

• Data Input: The device has a serial data input (DS) that allows for the shifting of data into the register.
• Shift Control: It features a shift clock input (SHCP) that controls the shifting of data through the register. On each rising edge of the clock, the data present at the DS input is shifted into the register.
• Output Control: The device includes a parallel output feature, allowing the contents of the shift register to be accessed simultaneously from multiple output pins (Q0 to Q7).
• Asynchronous Reset: The SN74LV166APWR has an active-low reset input (MR) that can clear the register, setting all outputs to a low state regardless of the clock input.

Performance Specifications:

• Propagation Delay: The typical propagation delay from the clock input to the output is around 15 ns at 5V, making it suitable for high-speed applications.
• Power Consumption: The device is designed to consume low power, which is beneficial for battery-operated devices and energy-efficient designs.
