The 74LV164DB is a high-performance, low-voltage, 8-bit serial-in/parallel-out shift register designed by NXP Semiconductors. This integrated circuit is part of the 74LV family, known for its low-voltage operation and compatibility with TTL levels. It is specifically engineered to operate in a broad range of applications, from industrial control systems to consumer electronics, offering a reliable solution for serial-to-parallel data conversion.

Key Features

• Operating Voltage: The device functions within a voltage range of 2.0 to 5.5V, making it suitable for interfacing with both 3.3V and 5V systems.
• High-Speed Operation: With a maximum clock frequency of 40 MHz at 5V, the 74LV164DB can handle high-speed data processing tasks efficiently.
• Low Power Consumption: The low-voltage operation translates to reduced power consumption, which is critical for battery-operated and power-sensitive applications.
• Output Drive Capability: The device can drive up to 15 LSTTL loads, providing ample current for most interfacing requirements.
• Edge-Triggered Clocking: The shift register utilizes a positive-edge triggered clock input, ensuring precise timing for data shifts.

Functional Description

The 74LV164DB consists of an 8-bit serial-in/parallel-out shift register with a straightforward interface. Data is entered serially through the Data Input (DS) pin when the clock (CP) input is pulsed. Each clock pulse shifts the data one bit position to the left, with the first bit entering Q0. The register is cleared by bringing the Master Reset (MR) input to a low logic level, which sets all outputs (Q0 to Q7) to a low state.

Applications

Due to its versatility and performance, the 74LV164DB is ideal for a variety of applications, including:

• Serial-to-parallel data conversion
• Remote control systems
• LED displays and indicators
• Sequential timing applications
• Interface circuitry
• Instrumentation and test equipment

With its robust design and NXP's commitment to quality, the 74LV164DB is a reliable choice for designers and engineers seeking a high-performance shift register solution.
