CD4006 18-Stage Static Shift Register

The CD4006 is an 18-stage static shift register from the 40xx series CMOS logic family. This device provides serial-in, serial-out operation with 18 master-slave flip-flop stages, making it suitable for delay line applications and serial data storage. The register shifts data on the rising edge of the clock input, and multiple tapping points are available for accessing intermediate stages.

The CD4006 is particularly useful for creating time delays in digital systems, serial data buffering, and as a building block for communication protocols. With its static operation, data is retained as long as power is applied and the clock is stopped. Standard CMOS features include wide supply voltage tolerance and low power consumption.
