SN74F574DW Octal D-Type Flip-Flops with 3-State Outputs

The SN74F574DW from Texas Instruments is a high-performance, octal edge-triggered D-type flip-flop integrated circuit. Designed for applications requiring the capture and storage of digital data, it is suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

With its 3-state outputs, the SN74F574DW can be connected directly to a bus-organized system. The 3-state feature allows for multiple outputs to be connected together for bus line applications without the need for external bus drivers. The non-inverting outputs further simplify the design process, making it a robust choice for digital systems.

This integrated circuit features a wide operating voltage range, typically from 4.5V to 5.5V, which allows for compatibility with standard TTL logic levels. The SN74F574DW operates at a temperature range from -40°C to 85°C, ensuring reliability across various environmental conditions. The device is packaged in a 20-pin SOIC (Small Outline Integrated Circuit), providing a compact footprint suitable for space-constrained applications.

Key features of the SN74F574DW include:

• Eight edge-triggered D-type flip-flops with individual D inputs and Q outputs.
• 3-state bus-driving outputs for bus-oriented applications.
• Wide operating voltage range compatible with TTL logic levels.
• High-current 3-state outputs can drive up to 15 LSTTL loads.
• Low power consumption characterized by a typical I_CC of only 40 µA in the off state.
• Direct bus connection when outputs are not in use.

The SN74F574DW is ideal for a wide range of digital applications including computers, data communications equipment, and control systems. Its high-speed performance and robust design ensure that it is a reliable choice for designers looking to create efficient and effective digital solutions.
