What the 300 mA sink rating means for your load
The SN75452BP: The open-collector output means the load connects between an external positive rail and the driver pin; the driver switches the ground path.
Housed in an 8-pin DIP (0.300-inch row spacing, 7.62 mm body width), the SN75452BP is a through-hole part shipped in tubes. The 8-PDIP footprint is a standard 0.100-inch pitch layout — no special pad geometry or thermal vias needed.
