4-bit bidirectional universal shift register
HEF40194B
MSI
DESCRIPTION
The HEF40194B is a 4-bit bidirectional shift register with
two mode control inputs (S
0
and S
1
), a clock input (CP), a
serial data shift left input (D
SL
), a serial data shift right input
(D
SR
), four parallel data inputs (P
0
to P
3
), an overriding
asynchronous master reset input (MR), and four buffered
parallel outputs (O
0
to O
3
). When LOW, MR resets all
stages and forces O
0
to O
3
LOW, overriding all other input
conditions. When MR is HIGH, the operation mode is
controlled by S
0
and S
1
as shown in the function table.
Serial and parallel operation are edge-triggered on the
LOW to HIGH transition of CP. The inputs at which the
data are to be entered and S
0
, S
1
must be stable for a
set-up time before the LOW to HIGH transition of CP.
