SM74HC595D

Shenzhen Sunmoon Micro · Shifting Register · SOP-16

SM74HC595D from Shenzhen Sunmoon Micro, 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 Q1 tri_state Parallel latched output bit 1 from the storage register. Three-state; enabled when /G (pin 13) is low.
2 Q2 tri_state Parallel latched output bit 2. Three-state, enabled by /G low.
3 Q3 tri_state Parallel latched output bit 3. Three-state, enabled by /G low.
4 Q4 tri_state Parallel latched output bit 4. Three-state, enabled by /G low.
5 Q5 tri_state Parallel latched output bit 5. Three-state, enabled by /G low.
6 Q6 tri_state Parallel latched output bit 6. Three-state, enabled by /G low.
7 Q7 tri_state Parallel latched output bit 7 (MSB of the 8-bit output). Three-state, enabled by /G low.
8 GND power_in Logic ground reference (0 V).
9 Q7' output Serial data output from the last stage of the shift register. Used to daisy-chain multiple 74HC595 devices; not three-state.
10 /SCLR input Active-low asynchronous shift-register clear. Driving low forces all shift-register bits to 0 (Q7' = 0); does not affect the storage latch until an RCK edge.
11 SCK input Shift-register clock. Data on SER is shifted into the shift register on the rising edge. Max 50 MHz (typ. 52 MHz at Vcc = 4.5 V).
12 RCK input Storage/latch register clock. On the rising edge, the shift-register contents are transferred to the output storage register (latched to Q0-Q7).
13 /G input Active-low output enable for the parallel outputs Q0-Q7. Low enables the latched data onto the outputs; high places Q0-Q7 in high-impedance (3-state).
14 SER input Serial data input to the shift register. Sampled on the rising edge of SCK; tSU ≈ 16 ns, tH ≈ 3 ns.
15 Q0 tri_state Parallel latched output bit 0 (LSB of the 8-bit output). Three-state, enabled by /G low.
16 VCC power_in Positive supply voltage, 2.0 V to 6.0 V. Bypass with 100 nF near the pin.

Ordering variants

Same part, different packaging or reel option.

  • SM74HC595DD

CAD (KiCad official)

  • Symbol: SM74HC595D
  • Footprint: Package_SO:SOIC-16_3.9x9.9mm_P1.27mm
  • 3D model: SOP-16 (KiCad packages3D, STEP)
  • 3D model files: sm74hc595d-etched.step / sm74hc595d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm74hc595d.step / sm74hc595d.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sm74hc595d.step 217 KB You want the bare part, or you mark your own boards.
sm74hc595d-etched.step 2.5 MB You want the part with SM74HC595D already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 618 faces against 267 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
