CD74HC243M96 from Texas Instruments, in a SOIC-14. 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. |
