When sizing the load, remember that both channels share the same package thermal path; driving both near the 300 mA limit simultaneously at 70°C ambient requires checking the derating curve. For a single relay or lamp load at 200 mA, the SN75451BP runs cool with margin. ## Through-hole 8-DIP — board fit and rework The 8-DIP (0.300\" row spacing) package is a through-hole part, which means it plugs into a socket or solders into plated-through holes. For prototyping, a DIP socket lets you swap drivers without desoldering. In production, through-hole adds assembly cost versus surface-mount, but for low-volume builds, legacy board repairs, or designs where vibration resistance from a socketed part matters, the 8-PDIP form factor is deliberate.","metaTitle":"SN75451BP Peripheral Driver, 300 mA, Open Collector, 8-DIP","metaDescription":"Texas Instruments SN75451BP dual peripheral driver with open-collector outputs, 300 mA per channel, 5 V supply, 8-DIP through-hole package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tube","Logic Type":"Peripheral Driver","Output Type":"Open Collector","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Number of Elements":"2","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"8-PDIP","Current - Output High, Low":"-, 300mA","Number of Bits per Element":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.94","priceTiers":[{"qty":1,"price":"$0.94000","currency":"USD"},{"qty":10,"price":"$0.84100","currency":"USD"},{"qty":25,"price":"$0.79840","currency":"USD"},{"qty":100,"price":"$0.65580","currency":"USD"},{"qty":250,"price":"$0.61304","currency":"USD"},{"qty":500,"price":"$0.54176","currency":"USD"},{"qty":1000,"price":"$0.42771","currency":"USD"},{"qty":2500,"price":"$0.40350","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7cc6335c8e9ef2a1672f10cc8b99a71e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN75451BP/alternatives.json"},"ai":{"faq":[{"question":"How much output current can SN75451BP drive?","answer":"Each of the two driver channels can sink up to 300 mA with the open-collector output.
