74HCT165D

Nexperia · Shift Registers · SOIC-16

74HCT165D from Nexperia, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); 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 to D7 is loaded into the shift register asynchronously.
2 CP input Clock input, LOW-to-HIGH edge-triggered; data is shifted on LOW-to-HIGH transitions when CE is LOW.
3 D4 input Parallel data input D4 (Dn), loaded into the register when PL is LOW.
4 D5 input Parallel data input D5 (Dn), loaded into the register when PL is LOW.
5 D6 input Parallel data input D6 (Dn), loaded into the register when PL is LOW.
6 D7 input Parallel data input D7 (Dn), loaded into the register when PL is LOW.
7 ~{Q7} output Complementary output from the last stage of the shift register.
8 GND power_in Ground (0 V).
9 Q7 output Serial output from the last stage of the shift register.
10 DS input Serial data input; when PL is HIGH, data enters the register serially at this pin.
11 D0 input Parallel data input D0 (Dn), loaded into the register when PL is LOW.
12 D1 input Parallel data input D1 (Dn), loaded into the register when PL is LOW.
13 D2 input Parallel data input D2 (Dn), loaded into the register when PL is LOW.
14 D3 input Parallel data input D3 (Dn), loaded into the register when PL is LOW.
15 CE input Clock enable input (active LOW); a HIGH on CE disables the CP input.
16 VCC power_in Positive supply voltage; for 74HCT165 the recommended range is 4.5 V to 5.5 V (Table 5, page 5).
