The MC74HC574AFL1 is an octal D-type flip-flop with 3-state outputs. This device contains eight edge-triggered D-type flip-flops with individual D inputs and 3-state outputs. It is commonly used in applications such as memory address registers, data latches, and interface circuits where data needs to be stored and retrieved.

Applications

• Memory address registers
• Data latches
• Interface circuits
• Buffer registers
• Microprocessor systems
• Data storage

Features

• High Speed Operation: tPD = 19 ns (typ) at VCC = 5V
• Low Power Dissipation: ICC = 4 μA (max) at TA = 25°C
• High Noise Immunity: VNIH = VNIL = 30 % VCC
• Operating Voltage Range: 2V to 6V
• Octal D-Type Flip-Flop
• Edge-Triggered D Inputs
• 3-State Outputs
• Common Clock and Output Enable

Benefits

• Fast data storage and retrieval.
• Low power consumption.
• Reliable operation in noisy environments.
• Ability to drive bus lines with three-state outputs.
• Simplified circuit design with common clock and output enable.
• Versatile use in various digital systems.

The MC74HC574AFL1 consists of eight D-type flip-flops that capture the value of their D inputs on the positive-going edge of the clock signal. The outputs are three-state, allowing them to be disabled (high impedance state) by asserting a high level on the output enable (OE) input. The device operates from a supply voltage of 2V to 6V and is compatible with standard TTL logic levels. It is commonly available in a surface mount package.
