TOSHIBA · Shift Registers · SOP-16

TC74HC165AF from TOSHIBA, in a SOP-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 SHIFT/LOAD input Shift/load control input: high enables serial shifting, low asynchronously loads parallel data A-H into the register.
2 CK input Clock input; parallel data loads and serial shifting occur on its positive-going transition.
3 E input Parallel data input E.
4 F input Parallel data input F.
5 G input Parallel data input G.
6 H input Parallel data input H.
7 QH_N output Complementary serial output of the last stage (inverted QH), drives 10 LSTTL loads.
8 GND power_in Ground supply pin.
9 QH output Serial output of the last (H) stage, drives 10 LSTTL loads.
10 SI input Serial data input, enabled when SHIFT/LOAD is high.
11 A input Parallel data input A.
12 B input Parallel data input B.
13 C input Parallel data input C.
14 D input Parallel data input D.
15 CK INH input Clock inhibit input; should be taken high only when CK is high.
16 VCC power_in Positive supply voltage, operating range 2 to 6 V.
