Dual 300 mA peripheral driver for inductive and lamp loads
It sits in the classic 75452 family — two independent driver channels in an 8-SOIC surface-mount package, intended for driving relays, solenoids, lamps, and small motors from TTL or 5 V CMOS logic. Active lifecycle status means no phase-out risk for current production builds.
300 mA sink — what it means for load selection
Each of the two open-collector outputs sinks 300 mA continuous. That is enough to pull in a 24 V relay coil or drive a 5 V incandescent lamp directly, but it is not a power-switch rating — you stay within the 300 mA per-channel ceiling. The open-collector stage means the load connects between an external supply (up to the transistor breakdown voltage, typically 30 V for this family) and the output pin; the driver pulls it low. No internal flyback diode is shown, so an external clamp diode across an inductive load is standard practice.
Supply and temperature — design-in constraints
That is fine for a regulated 5 V supply in a PLC, relay card, or motor-drive interface, but it will not tolerate the wider swings of an automotive or battery-powered system. If your ambient runs to 85°C or you need -40°C cold start, this is not the part.
Package and mounting — 8-SOIC footprint
Supplied in an 8-SOIC package (0.209" body width, 5.30 mm), the SN75452BPS is surface-mount only. The shipping medium is Tube. This is a standard SOIC footprint — no thermal pad, no exposed paddle — so power dissipation is through the leads and the PCB copper alone. At 300 mA per channel, the package temperature rise needs a quick check against the datasheet thermal resistance for your board stack-up.
