CD4018BPWE4 is a dual 4-bit binary ripple counter. It contains two 4-bit binary synchronous counters with reset capabilities that utilize Complementary MOS (CMOS) construction to achieve high speed and low power. The device has two independent 4-bit counters with each counter consisting of four D-type flip-flop stages C-A and C-B.

The CD4018BPWE4 logic family is designed for low power applications and is designed for use with an operating voltage range of 2.5V to 5.5V. The device is designed to hold state for a period of time in the event of a power outage or system reset. The device is used in low frequency applications where low power and low noise are important considerations.

The CD4018BPWE4 application field includes frequency synthesizers, metering, frequency dividers and counters, frequency conversion and modulation, pulse shapers and forming, telemetry, signal conditioning and pulse pattern recognition.

The device features two independent counters labeled C-A and C-B, which are two 4-bit binary synchronous counters. Each counter consists of four D-type flip-flop stages. The CMOS technologies allow these counters to operate at speeds up to 10 MHz and with low power consumption. An external clock signal (CLK IN) is connected to each of the C-A and C-B inputs, and uses the external clock signal to reset the counter to the binary count 0000.

The device also has four synchronous inhibit inputs, which act as enables for the counter. The four active low inhibit inputs are labeled DI-A, DI-B, DI-AB, and DI-C. When the DI-A or DI-B inputs are active, the C-A or C-B counters will not count, respectively. The DI-AB input inhibits both counters together, and the DI-C inhibits all four stages, regardless of the state of the other inhibit inputs.

The device features a reset input (R) which is used to reset the counter to the binary count 0000. It is an active low input and when chosen, it resets the counter regardless of the other inputs.The device also features two output pins labeled QA and QB. QA serves as an active high output of the C-A counter and QB is the active high output of the C-B.

In conclusion, CD4018BPWE4 is an ideal choice for low power, low noise applications that require high speed performance. It can be used for frequency synthesizers, frequency dividers, counters, signal conditioning and pulse pattern recognition.
