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 | OEB | input | Output-enable input for the B-port side; together with OEA it selects the data-flow direction (A to B or B to A) or places the I/O terminals in the high-impedance state per the truth table. |+| 2 | NC | unconnected | No internal connection. |+| 3 | A0 | bidirectional | Data I/O terminal for bus-transceiver channel 0 on the A side; acts as input or output (or high-Z) depending on the OEA/OEB control state. |+| 4 | A1 | bidirectional | Data I/O terminal for bus-transceiver channel 1 on the A side; acts as input or output (or high-Z) depending on the OEA/OEB control state. |+| 5 | A2 | bidirectional | Data I/O terminal for bus-transceiver channel 2 on the A side; acts as input or output (or high-Z) depending on the OEA/OEB control state. |+| 6 | A3 | bidirectional | Data I/O terminal for bus-transceiver channel 3 on the A side; acts as input or output (or high-Z) depending on the OEA/OEB control state. |+| 7 | GND | power_in | Ground/supply return terminal. |+| 8 | B3 | bidirectional | Data I/O terminal for bus-transceiver channel 3 on the B side; acts as input or output (or high-Z) depending on the OEA/OEB control state. |+| 9 | B2 | bidirectional | Data I/O terminal for bus-transceiver channel 2 on the B side; acts as input or output (or high-Z) depending on the OEA/OEB control state. |+| 10 | B1 | bidirectional | Data I/O terminal for bus-transceiver channel 1 on the B side; acts as input or output (or high-Z) depending on the OEA/OEB control state. |+| 11 | B0 | bidirectional | Data I/O terminal for bus-transceiver channel 0 on the B side; acts as input or output (or high-Z) depending on the OEA/OEB control state. |+| 12 | NC | unconnected | No internal connection. |+| 13 | OEA | input | Output-enable input for the A-port side; together with OEB it selects the data-flow direction (A to B or B to A) or places the I/O terminals in the high-impedance state per the truth table. |+| 14 | VCC | power_in | Positive supply voltage terminal, specified over 2V to 6V for HC types. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-14 |+| Category | Logic |+| Pins | 14 |++## CAD (KiCad official)++- Symbol: `CD74HC243M96`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-14 (KiCad packages3D, STEP)+- 3D model files: `cd74hc243m96-etched.step` / `cd74hc243m96-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cd74hc243m96.step` / `cd74hc243m96.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/cd74hct243) (24 pp, sha256 `40fb03b77b5d31c8`, retrieved 2026-09-22, tier: lcsc)+- **Datasheet language:** Chinese.
