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 | A0 | input | Address select input, least significant bit. TTL-compatible input selects one of eight outputs together with A1 and A2. |+| 2 | A1 | input | Address select input, middle bit. TTL-compatible input contributing to output selection. |+| 3 | A2 | input | Address select input, most significant bit. TTL-compatible input contributing to output selection. |+| 4 | E1 | input | Active-low enable input. Must be low along with E2 low and E3 high to enable decoder outputs; otherwise all outputs are low. |+| 5 | E2 | input | Active-low enable input. Must be low along with E1 low and E3 high to enable decoder outputs. |+| 6 | E3 | input | Active-high enable input. Must be high along with E1 and E2 low to enable decoder outputs. |+| 7 | Y7 | output | Decoded active-high output 7. Asserts high when A2:A0 = 111 and the device is enabled; otherwise low. |+| 8 | GND | power_in | Ground reference (0 V) for the device. |+| 9 | Y6 | output | Decoded active-high output 6. Asserts high when A2:A0 = 110 and the device is enabled. |+| 10 | Y5 | output | Decoded active-high output 5. Asserts high when A2:A0 = 101 and the device is enabled. |+| 11 | Y4 | output | Decoded active-high output 4. Asserts high when A2:A0 = 100 and the device is enabled. |+| 12 | Y3 | output | Decoded active-high output 3. Asserts high when A2:A0 = 011 and the device is enabled. |+| 13 | Y2 | output | Decoded active-high output 2. Asserts high when A2:A0 = 010 and the device is enabled. |+| 14 | Y1 | output | Decoded active-high output 1. Asserts high when A2:A0 = 001 and the device is enabled. |+| 15 | Y0 | output | Decoded active-high output 0. Asserts high when A2:A0 = 000 and the device is enabled. |+| 16 | VCC | power_in | Positive supply voltage input. Operating range 4.5 V to 5.5 V for HCT logic family. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOP-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++- `CD74HCT238M96`+- `CD74HCT238M96M`+- `CD74HCT238M96MT`+- `CD74HCT238M96E`+- `CD74HCT238M96EE4`+- `CD74HCT238M96PW`+- `CD74HCT238M96PWR`++## CAD (KiCad official)++- Symbol: `CD74HCT238M96`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/cd74hct238m96.pdf) (20 pp, sha256 `12903ef9d08d198b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
