The 74AHCT574D is a high-speed Si-gate CMOS device from NXP Semiconductors. It is designed to have the same high-speed performance of LSTTL combined with the true CMOS low power consumption. The 74AHCT574D is an octal D-type flip-flop that features eight edge-triggered, D-type flip-flops with individual D inputs and O outputs.
Key Features
- Logic Family: AHCT
- Logic Type: Octal D-type flip-flop
- Output Type: 3-State
- Propagation Delay Time: Typically 8 ns at 5V
- Operating Temperature: -40°C to +125°C
- Package: SO20
- Power Supply Voltage Range: 4.5V to 5.5V
Product Details
The 74AHCT574D is equipped with an active LOW output enable (OE) input, which, when HIGH, disables the outputs by placing them in a high impedance OFF-state. This feature allows for the use of common data lines or system buses. When OE is LOW, the device passes the data from the D inputs to the O outputs.
Another important feature of the 74AHCT574D is its edge-triggered design. The flip-flops capture data on the rising edge of the clock (CP) input, ensuring that the output state changes are synchronized with the clock signal. This is particularly useful for implementing sequential logic in a digital circuit where precise timing is crucial.
Applications
With its robust design and high-speed operation, the 74AHCT574D is suitable for a wide range of applications, including:
- Buffer/Storage Registers
- System Buses
- Data Storage and Transfer
- Control Registers
