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 | VCC | power_in | Logic supply voltage. Recommended 4.5 V to 5.5 V (absolute max 7 V). |+| 2 | SER IN | input | Serial data input to the 8-bit shift register. Sampled on the rising edge of SRCK. Setup time 1.6 ns min / 3 ns typ before SRCK rising edge. |+| 3 | DRAIN0 | output | Open-drain DMOS output 0. Sinks up to 100 mA continuous / 250 mA peak with a 33 V clamp. Off when the corresponding storage-register bit is low or when /G is high. |+| 4 | DRAIN1 | output | Open-drain DMOS output 1. Sinks up to 100 mA continuous / 250 mA peak with a 33 V clamp. |+| 5 | DRAIN2 | output | Open-drain DMOS output 2. Sinks up to 100 mA continuous / 250 mA peak with a 33 V clamp. |+| 6 | DRAIN3 | output | Open-drain DMOS output 3. Sinks up to 100 mA continuous / 250 mA peak with a 33 V clamp. |+| 7 | /CLR | input | Active-low shift-register clear. When low the input shift register is cleared; when high normal operation. Does not affect the storage register directly. |+| 8 | /G | input | Active-low output enable. When high all DMOS drain outputs are forced off (data in output buffer held low); when low data from the storage register drives the outputs. |+| 9 | SER OUT | output | Serial data output from the last stage of the shift register. Used to cascade multiple STPIC6C595 devices. |+| 10 | RCK | input | Register (storage) clock. Rising edge transfers shift-register contents into the 8-bit D-type storage register whose outputs drive the DMOS buffers. |+| 11 | DRAIN4 | output | Open-drain DMOS output 4. Sinks up to 100 mA continuous / 250 mA peak with a 33 V clamp. |+| 12 | DRAIN5 | output | Open-drain DMOS output 5. Sinks up to 100 mA continuous / 250 mA peak with a 33 V clamp. |+| 13 | DRAIN6 | output | Open-drain DMOS output 6. Sinks up to 100 mA continuous / 250 mA peak with a 33 V clamp. |+| 14 | DRAIN7 | output | Open-drain DMOS output 7. Sinks up to 100 mA continuous / 250 mA peak with a 33 V clamp. |+| 15 | SRCK | input | Shift-register clock. Rising edge clocks SER IN data into the shift register and shifts existing contents toward SER OUT. |+| 16 | GND | power_in | Ground reference for logic and DMOS source pins. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SO-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `STPIC6C595MTRMTR`+- `STPIC6C595MTRTTR`++## CAD (KiCad official)++- Symbol: `STPIC6C595MTR`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SO-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/stpic6c595mtr.pdf) (22 pp, sha256 `eeea45d02275800c`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
