SN74ABT574APWR Integrated Circuits (ICs)

Logic - Flip Flops

The SN74ABT574APWR is a 13-pin dual 4-wide input D-type flip flop. It is designed for general-purpose data storage applications, such as register and counter designs. This device features an internal output control for low power operation, allowing for low power consumption for applications that require low standby current.

Application Field

The SN74ABT574APWR is suitable for use as either a bi-stable flip flop or a single 4-wide latch. Use of a dual 4-wide input makes it suitable for applications such as a 4-bit counter, where two 4-bit data flow control channels can be used together. The SN74ABT574APWR is also suitable for use as a data storage flip flop in memory designs, and as a high-speed clock signal prescaler. Furthermore, the SN74ABT574APWR is designed for use in logic buses and interconnection networks.

Working Principle

The SN74ABT574APWR employs the mechanism of a typical dual 4-wide input D-type flip flop. Inputs A and B, as well as additional inputs G and H, can be used in either active-high or active-low configuration depending on the desired application. When both A and B are low, the flip flop will enter the low-power standby mode. When one of these two inputs transitions high, the flip flop will generate a signal on the output. This signal remains until either A or B become low again, at which point the flip flop re-enters the standby mode.

The SN74ABT574APWR features an internal output enable line, which is activated when both A and B are high. This output enable line is used to control the output signal generated by the flip flop, thus allowing for low power consumption when not in use. This internal output enable line can also be used to disable the output signal and thus reduce power consumption even further.

The SN74ABT574APWR is designed to provide reliable data transfer in both static and dynamic applications, thanks to its fast switching speed and low power consumption. Its low power operation is further augmented by an active-low input configuration that allows power to be conserved when the device is not actively storing data.

Conclusion

The SN74ABT574APWR is a versatile, low power, dual input D-type flip flop that is suitable for a wide range of data storage applications. Its internal output enable line allows for further power savings when the device is in standby mode, making it an ideal choice for low-power applications. The SN74ABT574APWR is highly reliable, and its low power operation and fast switching speed make it suitable for a wide range of storage applications.
