Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SSOP-20-208mil
SN74ABT244ADBR from Texas Instruments, in a SSOP-20-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |

| 3 | 2Y4 | tri_state | Three-state data output for buffer 2 bit 4, controlled by 2OE pin 19 |
| 4 | 1A2 | input | Data input for buffer 1 bit 2, non-inverted path to 1Y2 |
| 5 | 2Y3 | tri_state | Three-state data output for buffer 2 bit 3, controlled by 2OE pin 19 |
| 6 | 1A3 | input | Data input for buffer 1 bit 3, non-inverted path to 1Y3 |
| 7 | 2Y2 | tri_state | Three-state data output for buffer 2 bit 2, controlled by 2OE pin 19 |
| 8 | 1A4 | input | Data input for buffer 1 bit 4, non-inverted path to 1Y4 |
| 9 | 2Y1 | tri_state | Three-state data output for buffer 2 bit 1, controlled by 2OE pin 19 |
| 10 | GND | power_in | Ground reference |
| 11 | 2A1 | input | Data input for buffer 2 bit 1, non-inverted path to 2Y1 |
| 12 | 1Y4 | tri_state | Three-state data output for buffer 1 bit 4, controlled by 1OE pin 1 |
| 13 | 2A2 | input | Data input for buffer 2 bit 2, non-inverted path to 2Y2 |
| 14 | 1Y3 | tri_state | Three-state data output for buffer 1 bit 3, controlled by 1OE pin 1 |
| 15 | 2A3 | input | Data input for buffer 2 bit 3, non-inverted path to 2Y3 |
| 16 | 1Y2 | tri_state | Three-state data output for buffer 1 bit 2, controlled by 1OE pin 1 |
| 17 | 2A4 | input | Data input for buffer 2 bit 4, non-inverted path to 2Y4 |
| 18 | 1Y1 | tri_state | Three-state data output for buffer 1 bit 1, controlled by 1OE pin 1 |
| 19 | 2OE | input | Output Enable input for buffer 2; active-low control, when low enables 2Y1-2Y4 outputs, when high outputs are high-impedance |
| 20 | VCC | power_in | Positive supply voltage, recommended operating range 4.5 V to 5.5 V |
