74HC165D

Nexperia · Shifting Register · SOIC-16

74HC165D from Nexperia, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 /PL input Asynchronous parallel load input, active LOW. When LOW, data on D0-D7 is loaded into the shift register asynchronously.
2 CP input Clock input, LOW-to-HIGH edge-triggered. Data is shifted on the rising edge when /CE is LOW.
3 D4 input Parallel data input bit 4 (loaded into the shift register when /PL is LOW).
4 D5 input Parallel data input bit 5 (loaded into the shift register when /PL is LOW).
5 D6 input Parallel data input bit 6 (loaded into the shift register when /PL is LOW).
6 D7 input Parallel data input bit 7, the last (MSB-side) stage (loaded into the shift register when /PL is LOW).
7 /Q7 output Complementary (inverted) serial output from the last shift-register stage.
8 GND power_in Ground reference (0 V).
9 Q7 output Serial (non-inverted) output from the last shift-register stage.
10 DS input Serial data input. Data present here is shifted into the first stage on the LOW-to-HIGH clock transition (when /CE is LOW and /PL is HIGH).
11 D0 input Parallel data input bit 0 (loaded into the shift register when /PL is LOW).
12 D1 input Parallel data input bit 1 (loaded into the shift register when /PL is LOW).
13 D2 input Parallel data input bit 2 (loaded into the shift register when /PL is LOW).
14 D3 input Parallel data input bit 3 (loaded into the shift register when /PL is LOW).
15 /CE input Clock enable input, active LOW. When LOW, data is shifted on the rising edge of CP; a HIGH on /CE disables the CP input (hold).
16 VCC power_in Positive supply voltage. Recommended range 2.0 V to 6.0 V for 74HC165 (4.5-5.5 V for 74HCT165); absolute max 7 V.
