Description
The ’HC165 and ’HCT165 are 8-bit parallel or serial-in shift
registers with complementary serial outputs (Q
7
and Q
7
)
available from the last stage. When the parallel load (PL)
input is LOW, parallel data from the D0 to D7 inputs are
loaded into the register asynchronously. When the PL is
HIGH, data enters the register serially at the DS input and
shifts one place to the right (Q
0
→
Q
1
→
Q
2
, etc.) with each
positive-going clock transition. This feature allows parallel-
to-serial converter expansion by typing the Q
7
output to the
DS input of the succeeding device.
For predictable operation the LOW-to-HIGH transition of CE
should only take place while CP is HIGH. Also, CP an d CE
should be LOW before the LOW-to-HIGH transition of PL to
prevent shifting the data when PL goes HIGH.
