CD74ACT161E is a logic integrated circuit which can be classified in Logic - Counters, Dividers and has several application fields. This IC is based on a multi-stage ripple counter, for which the input clock can be used in generating a delayed output. It is an ideal choice for applications such as digital timing and sequencing, pulse shaping, pulse width modulation and so on.

The advantages of using the CD74ACT161E are its inherent compactness, which enables its usage in many applications, its dependability of the output and its low power consumption.

CD74ACT161E is a full 16-bit synchronous counter. This counter is divided into 4 sections of 4 bits. It works on a clock frequency of 20 MHz, which is 25% higher than the typical CMOS counter. This counter is composed of D-type flip-flops with preset, clear and clock inputs. It also includes four NAND gates, two of which are used to divide in two the two sections. It also includes two inverters, two scan paths and one auto reset.

CD74ACT161E has three main modes of operation. The first mode is referred to as Binary mode, where the output is loaded in the least significant bit and it increments through 2^16 - 1 bits. The second mode is referred to as BCD Mode, where the output is loaded into the least significant nibble and increments through 9999. The third mode is referred to as Universal Counter, in which the output is programmed by the user to have a maximum counter value and a minimum counter value. For example, if the user wants the output to increment between 0 and 10, the counter will count from 0 to 10 and then reset back to 0.

CD74ACT161E is also available with a buffered state output. This can be used in circumstances that require one of the outputs to stay active for a longer period of time. This output can be used to control the clock frequency of another counter or used as a reference signal for timing.

The main advantage of this type of IC is its low power consumption, which makes it perfect for application where space and power are the primary concerns. It is also ideal for applications that require an accurate and reliable output. This type of IC is well suited for applications such as motor speed control, digital timing and sequencing, pulse-width modulation, pulse shaping and so on.
