SN75452BDR 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, a TTL-compatible diode-clamped input with VIH ≥ 2V and VIL ≤ 0.8V, that must not float. |
| 2 | 1B | input | Channel 1 Logic Input B, a TTL-compatible diode-clamped input with VIH ≥ 2V and VIL ≤ 0.8V, that must not float. |
| 3 | 1Y | output | Channel 1 Driver, an open-collector output rated for 30V maximum off-state voltage and 300mA continuous collector current. |
| 4 | GND | power_in | Ground, circuit reference potential. |
| 5 | 2Y | output | Channel 2 Driver, an open-collector output rated for 30V maximum off-state voltage and 300mA continuous collector current. |
| 6 | 2A | input | Channel 2 Logic Input A, a TTL-compatible diode-clamped input with VIH ≥ 2V and VIL ≤ 0.8V, that must not float. |
| 7 | 2B | input | Channel 2 Logic Input B, a TTL-compatible diode-clamped input with VIH ≥ 2V and VIL ≤ 0.8V, that must not float. |
| 8 | VCC | power_in | Supply voltage input with recommended operating range of 4.75V to 5.25V for commercial-grade SN7545xB devices. |
