The HD74HC4022 is a four-stage Johson octal counter with built-in code converter.

High speed operation and spike-free outputs are obtained by use of a Johson octal counter design.

The eight decoded outputs are normally low, and go high only at their appropriate octal time period.

High Speed Operation High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table Clock L X Clock Enable X H L X H X X X: Irrelevant n < 4.
