74HC165BQ: 8-bit parallel-in/serial-out shift register
The 74HC165; 74HCT165 are high-speed Si-gate CMOS devices that comply with JEDEC standard no.
7A. They are pin compatible with Low-power Schottky TTL (LSTTL).
The 74HC165; 74HCT165 are 8-bit parallel-load or serial-in shift registers with complementary
serial outputs (Q7 and Q7) 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 PL is HIGH, data enters the register serially at the DS
input and shifts one place to the right (Q0 → Q1 → Q2, etc.) with each positive-going clock
transition. This feature allows parallel-to-serial converter expansion by tying the Q7 output
to the DS input of the succeeding stage.
The clock input is a gated-OR structure which allows one input to be used as an active LOW
clock enable (CE) input. The pin assignment for the CP and CE inputs is arbitrary and can be reversed for layout convenience.
The LOW-to-HIGH transition of input CE should only take place
while CP HIGH for predictable operation. Either the CP or the CE should be HIGH before the LOW-to-HIGH transition of PL to
prevent shifting the data when PL is activated.
