74HCT573DB,112

The 74HCT573DB,112 is a high-speed dual D-type flip-flop containing two non-clocked latches, commonly categorized as logic - latches. Each flip-flop is controlled by a separate clock, and the device can be used as two independent latches. The 74HCT573DB,112 also provides a reset or preset input to clear the latches, allowing them to be reset independent of the clock. The device is designed to be used in high speed memory address and data gating, high speed clock gating, and synchronous timing applications.

Application Field

One of the commonly used logic-latches, the 74HCT573DB, 112 is an ideal choice for applications where a high speed gate is required. This latch is capable of providing high speed gate with its two independent active-low clock inputs, which allows it to be used in memory address and data gating, high speed clock gating, and synchronous timing applications. The reset/preset functionality of this latch also makes it ideal for synchronous system control applications. The 74HCT573DB, 112 is also suitable for applications where level shifting is required in order to derive lower logic levels.

Working Principle

The 74HCT573DB, 112 flip-flop works on the principle of data storage and retrieval. The device has two active-low clock inputs (clock 1 and clock 2) and two data inputs. When the clock is low, the data is stored in a latch and can be retrieved when the clock is high. The reset/preset input is used to clear the latches independently of the clocks. When the reset/preset input is low, both latches are reset regardless of the clock state. This allows the device to be used in synchronous system control applications.

The 74HCT573DB, 112 is powered by a supply voltage of 3 to 5.5V and is capable of operating at clock speeds up to 20 MHz. The device has an output enable (OE) input for enabling or disabling the outputs. The output is tri-state, which means that it can be left in a high-impedance state when the output enable is high.

Conclusion

The 74HCT573DB, 112 is a high-speed dual D-type flip-flop containing two non-clocked latches, commonly used in logic - latch applications. This device can be used as two independent latches as it has two separate clock inputs. The reset/preset functionality of this latch also makes it ideal for synchronous system control applications. The output of the 74HCT573DB, 112 is tri-state, meaning it can be left in a high-impedance state when the output enable is high. The device is powered by a supply voltage of 3 to 5.5V and is capable of operating at clock speeds up to 20 MHz.
