TC426EOA from Microchip Tech, in a SOIC-8. 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 | NC | unconnected | No internal connection; this pin may be left unconnected. |
| 2 | IN A | input | Control input A is a TTL/CMOS compatible logic input. |
| 3 | GND | power_in | Ground reference for the device; individual ground returns for input and output circuits or a ground plane should be used. |
| 4 | IN B | input | Control input B is a TTL/CMOS compatible logic input. |
| 5 | OUT B | output | CMOS totem-pole output for driver B, specified as swinging within 25 mV of ground or the positive supply and rated for 1.5 A peak output current. |
| 6 | VDD | power_in | Supply input, 4.5 V to 18 V (absolute maximum supply is 20 V). |
| 7 | OUT A | output | CMOS totem-pole output for driver A, specified as swinging within 25 mV of ground or the positive supply and rated for 1.5 A peak output current. |
| 8 | NC | unconnected | No internal connection; this pin may be left unconnected. |
