The CD40161BPWR is a 16-bit counter or down counter (divider) designed for use in digital operating systems. It is capable of counting from 0 to 2^16 (65535) with each count represented by a pair of binary pulses. It is well suited for use in digital clock, stopwatch and timing applications. The input pulses are connected through an input pin, and the counter can be operated in either a parallel or serial mode.

The CD40161BPWR has two main components: an 8-bit counter and a 4-bit decoder. The 8-bit counter is used to keep track of the number of pulses received and to propagate their values to the decoder. The 4-bit decoder is used to convert the 8-bit binary representation of the count into a binary-coded decimal (BCD) value. This BCD value is what is used to output the desired count value.

The CD40161BPWR has four different operating modes; quasi-bidirectional, binary, straight binary and cascade. Quasi-bidirectional is used to count up or down without resetting to zero. Binary is used to count up from one to a set value and then reset back to one. Straight binary can count up or down to any specified value and will reset to the value specified. Cascade mode divides the input pulses by two, four or eight and outputs a binary number representing the divided value.

In addition to its different count modes, the CD40161BPWR includes a number of triggered outputs for different counting scenarios. It comes with an oscillator output that is used for triggering a reset to start or end a counting cycle. It also has a clocking output that can be used to prescaler the input pulses, as well as an enable output that can be used to pause or stop the counter or divider. The counter is designed to run at clock speeds of up to 1.2 MHz.

The CD40161BPWR is commonly used in digital display systems, such as digital clocks and stopwatches. It is also used for data acquisition and analysis as well as in industrial and commercial automation applications. The counter is available in various packages, including a 14-pin plastic dual in-line package, a 14-pin plastic thin shrink small-outline package, a 16-pin thin shrink small-outline package, and an 18-pin plastic thin shrink small-outline package.

The CD40161BPWR is a very versatile and powerful 16-bit counter or divider that can be used in a multitude of applications. Its programmability, wide range of supported operating modes, and triggered outputs make it ideal for digital systems that need to count or divide complex numbers or values.
