DESCRIPTION  
The M54/74HC195 is a high speed CMOS 4 BIT  
PIPO SHIFT REGISTER fabricated in silicon gate  
C2MOS technology. It has the same highspeed per-  
formance of LSTTL combined with true CMOS low  
power consumption.  
This shift register features parallel inputs, parallel  
outputs, J-K serial inputs, a SHIFT/LOAD control  
input, and a direct overriding CLEAR. This shift reg-  
ister can operate in two modes : Parallel Load ; Shift  
from QA towards QD.  
Parallel loading isaccomplished byapplying the four  
bits of data, and taking the SHIFT/LOAD control  
input low. The data is loaded into the associated flip  
flops and appears at the outputs after the positive  
transition of the clock input. During parallel loading,  
serial data flow is inhibited. Serial shifting occurs  
synchronously when the SHIFT/LOAD control input  
is high. Serial data for this mode is entered at the J-K  
inputs. These inputs allow the first stage to perform  
as a J-K or TOGGLE flip flop as shown in the truth-  
table.  
NC =  
No Internal  
All inputs are equipped with protection circuits  
against static discharge transient excess voltage.
