ON Semiconductor MC74AC574DWR2G Octal D-Type Flip-Flop

The MC74AC574DWR2G from ON Semiconductor is a high-performance, octal D-type flip-flop with a clear functionality. It is designed to provide essential features for a wide range of digital applications, particularly where the storage of multiple bits of data is required. This integrated circuit (IC) is a part of ON Semiconductor's AC series, which is known for its high-speed operation and compatibility with TTL (Transistor-Transistor Logic).

This device features eight edge-triggered flip-flops with individual D-type inputs and 3-state true outputs. The 3-state outputs are designed to drive bus lines or buffer memory address registers, which makes the MC74AC574DWR2G an ideal choice for interfacing with bus-oriented systems. The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time specifications with the LOW-to-HIGH transition of the clock (CLK) input.

The clear (CLR) input on the MC74AC574DWR2G can be used to set all eight of the flip-flop outputs to the low level by asserting a HIGH signal. This feature is particularly useful for initializing registers and memory devices during system power-up or for resetting the system during operation.

Key specifications of the MC74AC574DWR2G include:

• Logic Type: Octal D-Type Flip-Flop
