ON Semiconductor MC74ACT377N Octal D Flip-Flop
The MC74ACT377N is a high-performance, octal D flip-flop integrated circuit from ON Semiconductor, designed to provide reliable, high-speed operation for a variety of digital applications. Manufactured with advanced CMOS technology, this device features eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs.
The MC74ACT377N is part of the AC/ACT series, which is well-known for its robustness and compatibility with TTL (Transistor-Transistor Logic) levels, ensuring ease of integration into mixed-technology systems. The flip-flops in the MC74ACT377N are positive-edge triggered, meaning they capture data from their respective D inputs on the rising edge of the clock signal. Once captured, the data is held stable at the Q outputs until the next rising edge of the clock.
This device also includes a common clock (CP) input and a common output enable (OE) control, which is active low. When OE is low, the Q outputs will reflect the flip-flop states. If OE is high, the outputs will be in a high-impedance state, allowing for bus-oriented applications. This feature is particularly useful for multiplexing and data storage applications where output connectivity needs to be controlled.
The MC74ACT377N operates over a wide voltage range from 4.5V to 5.5V, which provides a good margin for standard 5V digital systems. Its low power consumption and high noise immunity are characteristics of the CMOS technology, making it a reliable choice for power-sensitive applications.
Encased in a plastic DIP (Dual In-line Package), the MC74ACT377N is designed for through-hole mounting, which is ideal for prototyping and educational purposes as well as commercial production. The device's pin configuration is industry-standard, which allows for drop-in replacement and easy upgrading of existing systems without significant redesign.
With its combination of high-speed operation, the versatility of use, and compatibility with existing logic levels, the MC74ACT377N from ON Semiconductor is a solid choice for designers looking to implement flip-flops in their digital circuits.
