ON Semiconductor 74AC374SJX: High-Speed CMOS Octal D-Type Flip-Flop

The 74AC374SJX from ON Semiconductor is a high-speed CMOS Octal D-Type Flip-Flop with 3-state outputs. This integrated circuit is designed to provide the reliability and performance required for modern digital systems. It is a member of the AC series, which is characterized by its high speed and low power consumption, making it ideal for a wide range of applications including computers, telecommunications, and other electronic systems.

The device features eight edge-triggered flip-flops with individual D-type inputs and 3-state outputs. The flip-flops capture the state of their individual D-inputs on the rising edge of the clock signal, C. Once captured, the data can be maintained or transferred to the outputs based on the status of the Output Enable (OE) input. When OE is low, the internal flip-flops' states are presented on the outputs. Conversely, when OE is high, the outputs are in a high-impedance state, which is essential for bus-oriented applications where multiple devices may need to share the same output lines.

The 74AC374SJX operates from a single 5V power supply and is characterized for operation from -40°C to 85°C, making it suitable for commercial environments. The device is packaged in a 20-lead small outline package (SOIC), with a "JX" suffix indicating the Pb-free version, which is compliant with RoHS (Restriction of Hazardous Substances) regulations, ensuring an environmentally friendly product.

Key features of the 74AC374SJX include:

• Eight D-type flip-flops with single clock and OE inputs
• 3-state outputs for bus-oriented applications
• High-speed operation: t_PD = 4.5 ns (typical) at V_CC = 5V
• Low power dissipation: I_CC = 4 μA (maximum) at T_A = 25°C
• Edge-triggered flip-flop design
• Inputs and outputs on opposite sides of the package for easy interface with microprocessors
• Useful in applications requiring high-speed data capture and transfer
• Lead-free and RoHS compliant

Overall, the 74AC374SJX from ON Semiconductor provides a robust and efficient solution for data storage and transfer in digital systems, ensuring high performance and compatibility with current environmental standards.
