The HD74LV374ATELL is an octal D-type flip-flop with 3-state outputs manufactured by Renesas Electronics America. This device features eight independent D-type flip-flops, each with a common clock input. The 3-state outputs allow for easy connection to a bus. It's part of the 74LV family, known for its low-voltage operation and high-speed performance. The 'ATELL' suffix likely specifies the package type and temperature range.

Applications:

• Data storage
• Registers
• Memory address latches
• Bus interfacing
• Microprocessor systems
• Low-voltage digital systems

Features:

• Octal D-Type Flip-Flop: Contains eight independent D-type flip-flops.
• Common Clock Input: All flip-flops are clocked simultaneously.
• 3-State Outputs: Allows for disconnecting the outputs from the bus.
• Low Voltage Operation: Operates at low voltage levels (typically 3.3V).
• High Speed Operation: Offers short propagation delays.
• CMOS Technology: Uses CMOS technology for low power consumption.
• ATELL Package: Likely refers to a small outline package.

Benefits:

• Efficient Data Storage: Provides an efficient way to store eight bits of data.
• Simplified System Design: Common clock input simplifies control logic.
• Flexible Bus Interfacing: 3-state outputs allow for easy bus sharing.
• Reduced Power Consumption: CMOS technology minimizes power dissipation.
• Increased System Performance: High-speed operation reduces propagation delays.
• Compatibility with Low-Voltage Systems: Operates at low voltage levels.
• Compact Size: ATELL package allows for high density mounting.

Technical Specifications: The HD74LV374ATELL typically operates from a 3.3V power supply, but often supports a wider range (e.g., 2V to 5.5V). It is available in a 20-pin TSSOP (Thin Shrink Small Outline Package) or similar package, denoted by ATELL. The operating temperature range is often extended, such as -40°C to +85°C or wider. Data is loaded into the flip-flops on the positive-going edge of the clock signal. The outputs are controlled by an output enable (OE) input.
