The CD4522BPWR is a dual 4-bit static CMOS counter/divider with external carry look-ahead which has two 4-bit up/down counters with individual count up/down and reset inputs. It is designed with low power and high speed CMOS technology in mind and can operate from a wide range of supply voltages (2V to 10V).The CD4522BPWR offers a wide range of features that make it an ideal choice for multiple application fields. It is generally used in applications such as time-controlled events, pulse/pattern generator and modulator, frequency division and multiplication, period timer and rate generator and counter/period acquisition and conversion. In addition to its versatility, the CD4522BPWR has enhanced durability and is capable of operating at temperatures up to 125 degrees C.The CD4522BPWR has two independent 4-bit up/down counters with individual count up/down and reset inputs. Each counter is capable of being reset by a logic “0” applied to the reset input, eliminating the need for additional control signals. This allows the counter to start counting at a user-defined value or reset.For up/down counting, the CD4522BPWR has two separate dual-inputs controls (one for each 4-bit counter) that define whether the counter will be counting up or down. When the counter is clocked, the bits in the counter will increment or decrement depending on the control inputs. In addition, an external carry-look-ahead logic is provided to allow for greater accuracy and speedier operations when larger numbers are involved.The CD4522BPWR also features a variety of operating modes, allowing it to be used for a wide range of applications. These include pulse pre-set, pulse post-set, time reset/pause, time reset/extend and time reset/repeat. Additionally, a wide range of output functions are available, such as divide-by-two, divide-by-four, clear-count-on-match, hold-count on-match and pulse-count-on-match.In conclusion, the CD4522BPWR offers an excellent combination of features and performances, making it ideal for a variety of applications including time-controlled events, pulse/pattern generator and modulator, frequency division and multiplication, period timer and rate generator and counter/period acquisition and conversion. Furthermore, it has enhanced durability and wide range of operating modes, allowing users to tailor the operation of the counter according to their needs and requirements.
