Overview
The CD4022BEE4 is a 4-stage Johnson counter produced by Texas Instruments. This integrated circuit is part of the CD4022B series, which features a fully static operation and is designed for medium-speed applications. The CD4022B counters have 8 decoded outputs and include inputs such as CLOCK, RESET, and CLOCK INHIBIT. The counters are advanced one count at the positive clock signal transition if the CLOCK INHIBIT signal is low, and the counter advancement is inhibited when the CLOCK INHIBIT signal is high. A high RESET signal clears the counter to its zero count.
