General Description

The CD4015BC contains two identical, 4-stage, serial input/parallel-output registers with independent “Data”, “Clock,” and “Reset” inputs. The logic level present at the input of each stage is transferred to the output of that stage at each positive-going clock transition. A logic high on the “Reset” input resets all four stages covered by that input. All inputs are protected from static discharge by a series

resistor and diode clamps to VDDand VSS.
