HCF4021  
Asynchronous parallel input or synchronous serial-in/serial-out  
8-stage static shift register  
Datasheet - production data  
Description  
The HCF4021 is a monolithic integrated circuit  
fabricated in metal oxide semiconductor  
technology available in PDIP-16 and SO-16  
PDIP-16  
SO-16  
packages.  
This device is an 8-stage parallel or serial-  
Features  
input/serial-output register having common clock  
and parallel/serial control inputs, a single serial  
data input, and individual parallel "jam" inputs to  
each register stage. Each register stage is a D-  
type, master-slave flip-flop in addition to an output  
from stage 8. "Q" outputs are also available from  
stages 6 and 7. Serial entry is synchronous with  
the clock but parallel entry is asynchronous.  
Medium speed operation: 12 MHz (typ.) clock  
rate at V - V = 10 V

Fully static operation  
8 master-slave flip-flops plus output buffering  
and control gating  
Quiescent current specified up to 20 V  
5 V, 10 V, and 15 V parametric ratings  
In this device, entry is controlled by the  
parallel/serial control input. When the  
Input leakage current I = 100 nA (max.) at  
I
parallel/serial control input is low, data are serially  
shifted into the 8-stage register synchronously  
with the positive transition of the clock line. When  
the parallel/serial control input is high, data are  
jammed into the 8-stage register via the parallel  
input lines and synchronous with the positive  
transition of the clock line. The clock input of the  
internal stage is “forced” when asynchronous  
parallel entry is made. Register expansion using  
multiple packages is permitted.
