8-bit static shift register
HEF4021B
MSI
DESCRIPTION
The HEF4021B is an 8-bit static shift register
(parallel-to-serial converter) with a synchronous serial
data input (D
S
), a clock input (CP), an asynchronous active
HIGH parallel load input (PL), eight asynchronous parallel
data inputs (P
0
to P
7
) and buffered parallel outputs from
the last three stages (0
5
to O
7
).
Each register stage is a D-type master-slave flip-flop with
a set direct/clear direct input. Information on P
0
to P
7
is
asynchronously loaded into the register while PL is HIGH,
independent of CP and DS. When PL is LOW, data on
D
S
is shifted into the first register position and all the data
in the register is shifted one position to the right on the
LOW to HIGH transition of CP. Schmitt-trigger action in the
clock input makes the circuit highly tolerant to slower clock
rise and fall times.
