FAQs

What is 74ACT574SC?

The 74ACT574SC is an octal D-type flip-flop with 3-state outputs, designed for use as an 8-bit register or storage register with common clock and common reset. It is commonly used in digital systems for temporary storage and data transfer applications.

How Does 74ACT574SC Work?

The 74ACT574SC operates by storing data at its inputs and transferring it to the outputs upon the rising edge of the clock signal. The 3-state outputs allow the device to be effectively disconnected from the bus, enabling multiple devices to share the same bus line. This flip-flop is commonly used in applications such as address latching, buffer storage, and data synchronization.

How Many Pins does 74ACT574SC have and What are the Functions of the Pinout Configuration?

The 74ACT574SC is housed in a 20-pin SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:

CP: Clock input for latching data.
DA(0-7): Data inputs for 8-bit parallel data.
OE: Output enable input for 3-state operation.
Q(0-7): Data outputs for 8-bit parallel data.
GND: Ground pin.
VCC: Power supply pin.
MR: Master reset input for clearing the register.

What are the Pros and Cons of 74ACT574SC?

Pros:

High-Speed Operation: Suitable for high-speed digital applications.
3-State Outputs: Allows for efficient bus sharing and multiple device connections.
Common Clock and Reset: Simplifies system timing and control synchronization.
Wide Operating Voltage Range: Compatible with various logic levels.

Cons:

Power Consumption: May have higher power consumption compared to lower-speed alternatives.
