SN74LVCZ245ADBR 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 | DIR | input | Direction-control input that selects A-to-B transfer when high and B-to-A transfer when low; inputs accept voltages up to 5.5 V with VCC from 2.7 V to 3.6 V. |
| 2 | A1 | bidirectional | 3-state data port A1 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 3 | A2 | bidirectional | 3-state data port A2 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 4 | A3 | bidirectional | 3-state data port A3 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 5 | A4 | bidirectional | 3-state data port A4 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 6 | A5 | bidirectional | 3-state data port A5 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 7 | A6 | bidirectional | 3-state data port A6 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 8 | A7 | bidirectional | 3-state data port A7 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 9 | A8 | bidirectional | 3-state data port A8 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 10 | GND | power_in | Ground reference pin; all unused inputs must be held at VCC or GND to ensure proper device operation. |
| 11 | B8 | bidirectional | 3-state data port B8 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 12 | B7 | bidirectional | 3-state data port B7 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 13 | B6 | bidirectional | 3-state data port B6 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 14 | B5 | bidirectional | 3-state data port B5 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 15 | B4 | bidirectional | 3-state data port B4 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 16 | B3 | bidirectional | 3-state data port B3 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 17 | B2 | bidirectional | 3-state data port B2 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 18 | B1 | bidirectional | 3-state data port B1 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V. |
| 19 | OE | input | Active-low output-enable input; a high level places the A and B ports in isolation, and OE should be tied to VCC through a pullup resistor to hold the high-impedance state above 1.5 V. |
| 20 | VCC | power_in | Supply voltage pin, specified for operation from 2.7 V to 3.6 V. |
