SN74LVT244BDBR 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 |
|---|---|---|---|
| 1 | 1OE | input | Active-low output-enable for bank 1 (1Y1-1Y4); drive HIGH to place bank-1 outputs in the high-impedance state. |
| 2 | 1A1 | input | Data input for bank 1, channel 1; accepts 0 V to 5.5 V (VI max) when VCC = 2.7 V-3.6 V. |
| 3 | 2Y4 | tri_state | 3-state output for bank 2, channel 4; IOH = −32 mA, IOL = 64 mA (recommended max at VCC = 3 V). |
