ON Semiconductor DM74LS174N Hex/Quad D-Type Flip-Flops with Clear
The ON Semiconductor DM74LS174N is a high-performance integrated circuit designed to provide reliable, high-speed flip-flop functionality with a clear feature. This device belongs to the 74LS family, which is known for its low-power Schottky technology, making it an excellent choice for a wide range of digital applications where power efficiency and speed are critical.
The DM74LS174N comprises six D-type flip-flops with direct clear (CLR) inputs. Each flip-flop has an independent data (D) input, a clock (CLK) input, and a clear input which can be used to reset the flip-flop to the low state. When the clear input is taken low, all six flip-flops are simultaneously cleared, regardless of the clock input condition. The flip-flops are edge-triggered, capturing the state of their respective D inputs on the rising edge of the clock, ensuring precise timing and synchronization across all six flip-flops.
Constructed with ON Semiconductor's robust technology, the DM74LS174N is characterized by its high noise immunity and low power consumption, making it an ideal choice for interfacing with high-speed and energy-sensitive systems. The device comes in a standard 16-pin DIP (Dual In-line Package), which is easy to handle and compatible with breadboards and traditional socket layouts, facilitating rapid prototyping and design integration.
Key features of the DM74LS174N include:
- Typical clock frequency of 35MHz, suitable for high-speed operations.
- Low power consumption, with a typical power dissipation of 80mW.
- Wide operating voltage range from 4.75V to 5.25V, ensuring compatibility with standard 5V systems.
- Direct clear input for resetting all flip-flops simultaneously.
- Edge-triggered from a low to high transition of the clock pulse.
- High noise immunity characteristic of 74LS logic family.
The ON Semiconductor DM74LS174N is an essential component for designers and engineers who require a reliable and efficient solution for data storage, signal processing, or control systems. Its ability to quickly clear all flip-flops and its fast response to clock inputs make it suitable for a variety of applications including registers, counters, and control circuits.
Whether you are working on a complex digital system or a simple logic control, the DM74LS174N offers the performance and reliability expected from a leading semiconductor manufacturer like ON Semiconductor.
