SN75451BPSR from Texas Instruments, in a SO-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 | 1A | input | Channel 1 logic input A for dual AND driver, TTL compatible with 0.8V to 2V input thresholds. |
| 2 | 1B | input | Channel 1 logic input B for dual AND driver, TTL compatible with 0.8V to 2V input thresholds. |
| 3 | 1Y | output | Channel 1 open collector output driver capable of sinking 300mA continuous at output voltages to 30V. |
| 4 | GND | power_in | Ground reference (0V circuit return). |
| 5 | 2Y | output | Channel 2 open collector output driver capable of sinking 300mA continuous at output voltages to 30V. |
| 6 | 2A | input | Channel 2 logic input A for dual AND driver, TTL compatible with 0.8V to 2V input thresholds. |
| 7 | 2B | input | Channel 2 logic input B for dual AND driver, TTL compatible with 0.8V to 2V input thresholds. |
| 8 | VCC | power_in | Supply voltage; recommended operating range 4.75V to 5.25V for commercial grade SN7545xB. |
