The CD4015BC contains two identical, 4-stage, serialinput/ 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 VDD and VSS. Features Wide supply voltage range: 3.0V to 18V High noise immunity: 0.45 VDD (typ.) Low power TTL: Fan out of 2 driving 74L compatibility: or 1 driving 74LS Medium speed operation: 8 MHz (typ.) clock rate Fully static design: @VDD − VSS = 10V Applications • Serial-input/parallel-output data queueing • Serial to parallel data conversion • General purpose register
