The CD4022BNSRE4 belongs to the family of logic circuits known as counters, dividers, and registers. This circuit is an eight-stage binary ripple counter. It’s designed for operating off a supply voltage as low as 4.5V and a maximum of 18V.

The CD4022BNSRE4 is commonly used for applications such as clock division, frequency division, pulse counting, timing operations, pulse width measurement, and instrumentation.

The counter increments the count on the negative edge of each clock pulse, with each positive edge of the clock resetting the count to 0. To prevent the counter from resetting before the count is complete, the clock pulse must remain high for at least 30ns.

The CD4022BNSRE4 is also characterized by low power consumption, high speed performance, and low noise. The device is offered in a small size package with two 3-state outputs that enable multi-way selection and fan-out loads.

The device has an output enable pin (OE), which permits synchronization without additional gating. When set high, all outputs are set to the high-impedance state regardless of the clock level.

The reset input (R) puts the 8bit counter into the reset condition. When reset is low, all outputs are reset to "0", independent of the clock pulse. The reset input must remain low for a minimum of 50nS for the reset condition to be active.

The clock input (Ck) is used to clock the counters. This input must be kept high for at least 30nS for a valid clock pulse. Upon receiving a clock, the output state at that time will be counted.

The CD4022BNSRE4 counter is a powerful and versatile tool that can be used in a variety of applications. It offers reliable performance and a cost-effective solution for most digital counter implementations.
