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

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
