ON Semiconductor MC74ACT74DR2G Dual D-Type Positive Edge-Triggered Flip-Flop

The MC74ACT74DR2G from ON Semiconductor is a high-performance, dual D-type positive edge-triggered flip-flop integrated circuit, designed for use in a broad range of applications. This device is part of the AC series, which is characterized by its fast switching speeds and high noise immunity, making it suitable for operating in demanding environments.

Constructed with advanced CMOS technology, the MC74ACT74DR2G offers significant power savings while maintaining high-speed operation. It operates with a supply voltage ranging from 4.5V to 5.5V, which is typical for 5V digital systems, providing a convenient interface with standard logic levels.

Each flip-flop has individual clear and set inputs, as well as a clock input. The clear and set inputs are asynchronous, ensuring that the flip-flop can be reset or preset independently of the clock signal, allowing for greater flexibility in timing operations. The outputs can switch to the high or low state on the rising edge of the clock pulse, providing precise control over the output signals.

The MC74ACT74DR2G is available in an SOIC-14 package, which is a small outline integrated circuit package that is designed for surface mounting on printed circuit boards. This package is widely used in the industry due to its compact footprint and ease of soldering, making it an excellent choice for space-constrained applications.

This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. This feature is particularly useful in battery-powered devices, where power conservation is critical.

The MC74ACT74DR2G is a versatile component that is ideal for a variety of applications, including control and state machine logic in computers and peripherals, register design, and as a part of more complex integrated circuits. With its robust design and ON Semiconductor's commitment to quality, this flip-flop is a reliable choice for designers looking to add edge-triggered flip-flop functionality to their digital systems.
