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 data output bit 1. 3-state output; high-impedance when OE is HIGH. Drives ±8 mA at VCC = 4.5 V (VOH ≥ 3.94 V, VOL ≤ 0.36 V typical). |+| 2 | Q2 | tri_state | Parallel data output bit 2. 3-state output; high-impedance when OE is HIGH. |+| 3 | Q3 | tri_state | Parallel data output bit 3. 3-state output; high-impedance when OE is HIGH. |+| 4 | Q4 | tri_state | Parallel data output bit 4. 3-state output; high-impedance when OE is HIGH. |+| 5 | Q5 | tri_state | Parallel data output bit 5. 3-state output; high-impedance when OE is HIGH. |+| 6 | Q6 | tri_state | Parallel data output bit 6. 3-state output; high-impedance when OE is HIGH. |+| 7 | Q7 | tri_state | Parallel data output bit 7. 3-state output; high-impedance when OE is HIGH. |+| 8 | GND | power_in | Ground reference (0 V). Max IGND = -75 mA. |+| 9 | Q7S | output | Serial data output from the last shift register stage (Q7 of the shift register, not the storage register). Used to cascade multiple 595s. Not 3-stated by OE. |+| 10 | MR | input | Master reset, active LOW. A LOW asynchronously clears the shift register only (storage register/parallel outputs unaffected until STCP is clocked). Schmitt-trigger input, overvoltage tolerant to 5.5 V. |+| 11 | SHCP | input | Shift register clock input. Data on DS is shifted on the LOW-to-HIGH transition. Max frequency 130 MHz (VCC 4.5-5.5 V). Schmitt-trigger input. |+| 12 | STCP | input | Storage register clock input. A LOW-to-HIGH transition transfers the shift register contents to the 8-bit storage register and to the parallel outputs. Schmitt-trigger input. |+| 13 | OE | input | Output enable, active LOW. A HIGH forces Q0-Q7 into the high-impedance OFF-state; does not affect the shift or storage register contents. Schmitt-trigger input. |+| 14 | DS | input | Serial data input to the shift register. Sampled on the LOW-to-HIGH edge of SHCP. Schmitt-trigger input, overvoltage tolerant to 5.5 V. |+| 15 | Q0 | tri_state | Parallel data output bit 0. 3-state output; high-impedance when OE is HIGH. |+| 16 | VCC | power_in | Supply voltage. 2.0 V to 5.5 V (74AHC595); 4.5 V to 5.5 V (74AHCT595). Absolute max 7.0 V. Recommend local 0.1 µF decoupling to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | TSSOP-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `74AHC595PW`+- `74AHC595PWD`+- `74AHC595PWBQ`++## CAD (KiCad official)++- Symbol: `74AHC595PW`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Nexperia datasheet](https://assets.nexperia.com/documents/data-sheet/74AHC595PW.pdf) (19 pp, sha256 `67d6cf86d0a75a0a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
