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 | S1 | output | Sum output bit 1. Push-pull CMOS output representing bit 1 of the 4-bit sum of A + B + CIN. |+| 2 | B1 | input | Operand B input bit 1. CMOS logic input for bit 1 of the B addend. |+| 3 | A1 | input | Operand A input bit 1. CMOS logic input for bit 1 of the A addend. |+| 4 | S0 | output | Sum output bit 0 (LSB). Push-pull CMOS output representing the least-significant bit of the 4-bit sum. |+| 5 | A0 | input | Operand A input bit 0 (LSB). CMOS logic input for the least-significant bit of the A addend. |+| 6 | B0 | input | Operand B input bit 0 (LSB). CMOS logic input for the least-significant bit of the B addend. |+| 7 | CIN | input | Carry input. CMOS logic input for the carry-in bit added into the LSB stage. When using positive logic and no carry-in is present, this input must be tied low. |+| 8 | GND | power_in | Ground reference (0 V). Negative supply return. |+| 9 | COUT | output | Carry output. Push-pull CMOS output that goes active when the 4-bit sum exceeds 15, providing the carry-out for cascading to the next adder stage. |+| 10 | S3 | output | Sum output bit 3 (MSB). Push-pull CMOS output representing the most-significant bit of the 4-bit sum. |+| 11 | B3 | input | Operand B input bit 3 (MSB). CMOS logic input for the most-significant bit of the B addend. |+| 12 | A3 | input | Operand A input bit 3 (MSB). CMOS logic input for the most-significant bit of the A addend. |+| 13 | S2 | output | Sum output bit 2. Push-pull CMOS output representing bit 2 of the 4-bit sum. |+| 14 | A2 | input | Operand A input bit 2. CMOS logic input for bit 2 of the A addend. |+| 15 | B2 | input | Operand B input bit 2. CMOS logic input for bit 2 of the B addend. |+| 16 | VCC | power_in | Positive supply voltage. HC types: 2 V to 6 V. HCT types: 4.5 V to 5.5 V. Bypass with a 0.1 uF (and optionally 1 uF) capacitor placed close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `CD74HC283M96`+- `CD74HC283M96M`+- `CD74HC283M96MT`+- `CD74HC283M96E`+- `CD74HC283M96N`+- `CD74HC283M96F`+- `CD74HC283M96J`++## CAD (KiCad official)++- Symbol: `CD74HC283M96`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/cd54hc283) (20 pp, sha256 `986ef7f872e3d2c3`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
