SN75451BD from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1A | input | Channel 1 logic input A; accepts TTL-compatible voltage from 0V to 5.5V absolute maximum with internal clamping diode. |
| 2 | 1B | input | Channel 1 logic input B; accepts TTL-compatible voltage from 0V to 5.5V absolute maximum with internal clamping diode. |
| 3 | 1Y | output | Channel 1 open-collector output driver; sinks up to 300mA recommended or 400mA absolute maximum current at output voltages to 30V. |
| 4 | GND | power_in | Ground reference, return path for all circuit currents. |
| 5 | 2Y | output | Channel 2 open-collector output driver; sinks up to 300mA recommended or 400mA absolute maximum current at output voltages to 30V. |
| 6 | 2A | input | Channel 2 logic input A; accepts TTL-compatible voltage from 0V to 5.5V absolute maximum with internal clamping diode. |
| 7 | 2B | input | Channel 2 logic input B; accepts TTL-compatible voltage from 0V to 5.5V absolute maximum with internal clamping diode. |
| 8 | VCC | power_in | Supply voltage 4.75V to 5.25V for SN7545xB; requires 0.1µF bypass capacitor per power supply recommendations. |
