Description

The 74LV74D is a dual D-type flip-flop with set and reset features, designed for low-voltage and high-speed applications. It's part of the 74LV series, which is compatible with TTL (Transistor-Transistor Logic) and features low power consumption. Each flip-flop within the component has a data input (D), a clock input (CP), an asynchronous set (SD), and an asynchronous reset (RD), and it provides a complementary output (Q and Q̅).
The device operates with a supply voltage range of 1.0V to 5.5V, making it suitable for battery-powered operations and interfacing with other digital systems. It's often used in applications requiring data storage, data transfer, or digital logic operations. The 74LV74D is commonly packaged in small-outline packages (SOP) for space-saving in circuit designs.
Its ability to store binary data and maintain its state until reset or updated by the clock signal makes it essential in sequential logic circuits like counters, shift registers, and memory units. The robust design ensures reliable performance across a broad range of temperatures and electrical conditions.

Features

The 74LV74D is a dual positive-edge triggered D-type flip-flop with a direct set and reset option. Key features include:
1. Logic Family: Part of the Low-Voltage CMOS (74LV) family, ensuring low power consumption and high noise immunity.
2. Voltage Range: Operates over a wide voltage range of 1.0V to 5.5V, making it versatile for various applications.
3. Edge-Triggered: Data is transferred to the output on the rising edge of the clock signal.
4. Direct Set and Reset: Asynchronous inputs allow the flip-flops to be set or reset independently of the clock signal.
5. Output Capability: Standard outputs, capable of sourcing and sinking current, suitable for driving typical TTL loads.
6. Propagation Delay: Low propagation delay, ensuring quick operation, suitable for high-speed applications.
7. ESD Protection: Includes protection against electrostatic discharge, enhancing device reliability.
8. Packaging: Available in various small-outline packages (e.g., SO, SSOP, TSSOP), supporting compact design requirements.
These features make the 74LV74D suitable for use in digital systems requiring flip-flop functionalities, such as data storage, data transfer, and frequency division.

Package

The 74LV74D is a dual D-type flip-flop integrated circuit, and it comes in a surface-mount package. Specifically, it is typically available in a SO-14 (Small Outline) package, which is a 14-pin configuration.

Pinout

The 74LV74D is a dual D-type flip-flop integrated circuit with a pin count of 14. It features two independent D-type flip-flops with individual data (D), clock (CP), preset (PRE), and clear (CLR) inputs. Each flip-flop has complementary outputs, Q and Q̅.
Key functions include:
- D (Data Input): Captures the input data on the rising edge of the clock.
- CP (Clock Input): Triggers the storage of data on its rising edge.
- PRE (Preset Input): Sets the Q output to high when activated, independent of the clock.
- CLR (Clear Input): Resets the Q output to low when activated, independent of the clock.
- Q and Q̅ (Outputs): Provide the stored data and its complement, respectively.
The 74LV74D is often used in digital circuits for data storage, synchronization, and frequency division. Its low-voltage technology ensures compatibility with modern low-power systems.
