The MC74ACT161DG is a member of the Advanced CMOS Logic (ACL) family of logic. It is a synchronous high speed 4-bit binary up counter that is an ideal choice for wide variety of applications. The device offers several advantages of ACL technology over earlier bipolar devices, including significantly lower power/cost, improved output sinking/sourcing capability, higher speed and improved noise immunity.

The MC74ACT161DG can be used as a counter or dividing logic in many applications. It is especially suitable for applications that require low power consumption and fast counting time. The operations of the device can be characterized as synchronous, 4-bit binary up counter with divide-by-2, divide-by-4 and divide-by-8 outputs, allowing it to be used in a variety of applications related to counting, timing and frequency division. The device also has an asynchronous reset input, allowing it to be set to any predetermined count value.

The MC74ACT161DG’s working principle is based on the functionality of a 4-bit counter. It has four input pins, R0, R1, R2, R3, as well as a Clock Input (CP) and an asynchronous Reset Input (MR). When a high-to-low transition is applied to the Clock Input, the state of the four bits is incremented by one. The Reset Input allows the user to preset the counter to the known value. The device also has four Division Outputs (Q0, Q1, Q2, Q3), which correspond to the four bits of the counter. Each of these outputs can be used to divide the applied frequency of the Clock Input.

The MC74ACT161DG is a CMOS synchronous up-counter that is commonly used in applications that require precise counting in a very short amount of time. It is a popular choice for portable and automotive applications that tend to be more power sensitive. Its low power consumption and fast counting capability make it a good choice for applications such as precise timing and frequency division, as well as various logic control and data acquisition applications. With its advanced technology, high performance, and reliable operation, the MC74ACT161DG is an excellent device for any application where precise timing and frequency division is required.
