DESCRIPTION

The HEF40195B is a fully synchronous edge-triggered
4-bit shift register with a clock input (CP), four synchronous
parallel data inputs (P0to P3), two synchronous serial data
inputs (J, K), a synchronous parallel enable input (PE),
buffered parallel outputs from all 4-bit positions (O0to O3),
a buffered inverted output from the last bit position (O3)
and an overriding asynchronous master reset input (MR).
Each register stage is of a D-type master-slave flip-flop.
Operation is synchronous (except for MR) and is
edge-triggered on the LOW to HIGH transition of the CP

input. When

PE is LOW, data are loaded into the register
from P0to P3on the LOW to HIGH transition of CP. When
PE is HIGH, data are shifted into the first register position
from J and K and all the data in the register are shifted one
position to the right on the LOW to HIGH transition of CP.
D-type entry is obtained by interconnecting J and K.
When J is HIGH and K is LOW, the first stage is in the
toggle mode. When J is LOW andK is HIGH, the first stage
is in the hold mode.
A LOW on MR resets all four bit positions (O0to
O3= LOW, O3= HIGH) independent of all other input
conditions.
