High-Speed CMOS Octal D-Type Flip-Flop with 3-State Outputs

Reliable 8-Bit Data Storage for High-Performance Applications

The NTE74HC574 is a high-speed CMOS octal D-type flip-flop designed for demanding digital systems that require rapid, accurate data latching and reliable bus interfacing. Featuring 3-state outputs, this device is ideal for use in microprocessor systems, memory address latching, and parallel data transfer applications.

Key Features

• Eight edge-triggered D flip-flops in a single package
• High-speed CMOS technology for fast data latching
• 3-state non-inverting outputs for efficient bus interfacing
• Tristate control for easy integration in multiplexed systems

Technical Data

• Logic Family: High-speed CMOS
• Configuration: Octal D-type flip-flop
• Output Type: 3-state
• Edge Triggered: Yes
• QTY Per Package: 1
• NTE Part Number: NTE74HC574

Usage Instructions

On the rising edge of the clock pulse, data present at each D input is transferred to the corresponding Q output. When the Output Enable (OE) control is high, all eight outputs assume a high-impedance state, allowing for direct connection to shared data buses without signal contention.

Applications

• Microprocessor and microcontroller interface
• Memory data/address latching
• Bus-oriented systems
• Industrial automation and instrumentation
