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 | DIR | input | Direction control input. When DIR = L, data flows from the B bus to the A bus; when DIR = H, data flows from the A bus to the B bus. CMOS/LSTTL-compatible logic input. |+| 2 | A0 | bidirectional | Bidirectional data I/O, channel 0 of the A-side bus. Acts as an input when DIR = H (data flows to B0) and as a 3-state output when DIR = L. High-Z when OE = H. |+| 3 | A1 | bidirectional | Bidirectional data I/O, channel 1 of the A-side bus. Paired with B1 through the internal transceiver. |+| 4 | A2 | bidirectional | Bidirectional data I/O, channel 2 of the A-side bus. Paired with B2 through the internal transceiver. |+| 5 | A3 | bidirectional | Bidirectional data I/O, channel 3 of the A-side bus. Paired with B3 through the internal transceiver. |+| 6 | A4 | bidirectional | Bidirectional data I/O, channel 4 of the A-side bus. Paired with B4 through the internal transceiver. |+| 7 | A5 | bidirectional | Bidirectional data I/O, channel 5 of the A-side bus. Paired with B5 through the internal transceiver. |+| 8 | A6 | bidirectional | Bidirectional data I/O, channel 6 of the A-side bus. Paired with B6 through the internal transceiver. |+| 9 | A7 | bidirectional | Bidirectional data I/O, channel 7 of the A-side bus. Paired with B7 through the internal transceiver. |+| 10 | GND | power_in | Ground reference (0 V). Tie to system ground. |+| 11 | B7 | bidirectional | Bidirectional data I/O, channel 7 of the B-side bus. Paired with A7 through the internal transceiver. |+| 12 | B6 | bidirectional | Bidirectional data I/O, channel 6 of the B-side bus. Paired with A6 through the internal transceiver. |+| 13 | B5 | bidirectional | Bidirectional data I/O, channel 5 of the B-side bus. Paired with A5 through the internal transceiver. |+| 14 | B4 | bidirectional | Bidirectional data I/O, channel 4 of the B-side bus. Paired with A4 through the internal transceiver. |+| 15 | B3 | bidirectional | Bidirectional data I/O, channel 3 of the B-side bus. Paired with A3 through the internal transceiver. |+| 16 | B2 | bidirectional | Bidirectional data I/O, channel 2 of the B-side bus. Paired with A2 through the internal transceiver. |+| 17 | B1 | bidirectional | Bidirectional data I/O, channel 1 of the B-side bus. Paired with A1 through the internal transceiver. |+| 18 | B0 | bidirectional | Bidirectional data I/O, channel 0 of the B-side bus. Paired with A0 through the internal transceiver. |+| 19 | OE | input | Active-low output enable. When OE = L, the transceiver is enabled and drives in the direction set by DIR. When OE = H, both A and B I/O ports are placed in the high-impedance (isolation) state. |+| 20 | VCC | power_in | Positive supply. HC types: 2 V to 6 V; HCT types: 4.5 V to 5.5 V. Decouple with a 0.1 µF (and optional 1 µF) bypass capacitor as close to the pin as possible. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-20-300mil |+| Category | Logic |+| Pins | 20 |++## Ordering variants++- `CD74HC245M96`+- `CD74HC245M96M`+- `CD74HC245M96E`+- `CD74HC245M96EE4`+- `CD74HC245M96F`+- `CD74HC245M96F3A`++## CAD (KiCad official)++- Symbol: `CD74HC245M96`+- Footprint: `Package_SO:SOIC-20W_7.5x12.8mm_P1.27mm`+- 3D model: SOIC-20-300mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/cd74hc245m96-datasheet.pdf) (None pp, sha256 `7d20206cdfd20934`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
