SN74HC574N

The SN74HC574N is a high-performance CMOS octal edge-triggered D-type flip-flop with 3-state outputs. It is specifically designed for use in digital systems where reliable data latching, timing control, and bus-driving capabilities are required.

Key Features:

1. Octal Configuration:

   • The SN74HC574N contains eight independent D-type flip-flops, each with its own dedicated data input (D).

2. Edge-Triggered Operation:

   • The flip-flops are triggered on the positive edge (low-to-high transition) of the clock (CLK) input.

3. 3-State Outputs:

   • The outputs of the flip-flops can be placed in either a normal logic state (high or low) or a high-impedance state via a buffered output-enable (OE) input.
   • In the high-impedance state, the outputs neither load nor drive the bus lines significantly, allowing for easy interfacing with other devices on the bus.

4. Wide Operating Voltage Range:

   • The SN74HC574N operates over a wide voltage range of 2V to 6V, making it suitable for use in a variety of digital circuits.

5. High-Speed Performance:

   • With fast propagation delays, typically around 22ns, the SN74HC574N can handle high-frequency signals with ease.

6. Low Power Consumption:

   • The IC consumes low power, with a maximum ICC of 80µA, making it energy-efficient and suitable for use in battery-powered devices.

7. Bus-Structured Pinout:

   • The pinout of the SN74HC574N is structured for bus applications, with a common clock (CLK) and output-enable (OE) input for all flip-flops, and separate data inputs and outputs for each flip-flop.

8. Package Options:

   • The SN74HC574N is available in various package options, including DIP-20, SOIC, SSOP, and TSSOP, allowing for flexible integration into existing circuits.

Applications:

• The SN74HC574N is ideal for use in a wide range of digital applications, including buffer registers, I/O ports, bidirectional bus drivers, and working registers.
• It can be used in microprocessor systems, memory interfaces, and other digital circuits where reliable data latching and timing control are required.

In summary, the SN74HC574N is a versatile and reliable octal edge-triggered D-type flip-flop with 3-state outputs, suitable for use in a wide range of digital systems. Its high-performance CMOS technology, fast propagation delays, low power consumption, and bus-structured pinout make it an ideal choice for applications requiring reliable data latching, timing control, and bus-driving capabilities.
