74HC165D-JSM

JSMSEMI · Shift Registers · SOP-16

74HC165D-JSM from JSMSEMI, in a SOP-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 SH/LD input Shift/Load control input; LOW loads parallel inputs A-H into the register, HIGH enables serial shift operation on the rising clock edge.
2 CLK input Clock input; register shifts on rising edge when SH/LD is HIGH and CLK INH is LOW; interchangeable with CLK INH.
3 E input Parallel data input E; loaded into the fifth register stage when SH/LD is LOW (parallel load).
4 F input Parallel data input F; loaded into the sixth register stage when SH/LD is LOW (parallel load).
5 G input Parallel data input G; loaded into the seventh register stage when SH/LD is LOW (parallel load).
6 H input Parallel data input H; loaded into the eighth (last) register stage when SH/LD is LOW (parallel load).
7 ~QH output Complementary serial output; inverted QH from the last shift-register stage; can drive up to 10 LSTTL loads.
8 GND power_in Ground reference; 0 V supply rail.
9 QH output Serial data output; data from the last (H) register stage shifted out MSB-first; can drive up to 10 LSTTL loads.
10 SER input Serial data input; data present at SER is shifted into the first register stage on each rising clock edge during shift operation.
11 A input Parallel data input A; loaded into the first register stage when SH/LD is LOW (parallel load).
12 B input Parallel data input B; loaded into the second register stage when SH/LD is LOW (parallel load).
13 C input Parallel data input C; loaded into the third register stage when SH/LD is LOW (parallel load).
14 D input Parallel data input D; loaded into the fourth register stage when SH/LD is LOW (parallel load).
15 CLK INH input Clock inhibit input; HIGH level inhibits all clock transitions; LOW level allows clocking; interchangeable with CLK.
16 VCC power_in Positive supply voltage; recommended operating range 2 V to 6 V; absolute maximum -0.5 V to 7 V.
