Each of the two driver elements can sink 300 mA continuously when the output is low. That is enough current to pull in a standard 5 V relay coil (typically 50–150 mA) or drive a small incandescent lamp directly. The open-collector output means the load connects between an external supply (up to the driver's breakdown voltage, typically 30 V or higher for this family) and the output pin; the driver pulls the pin low to energise the load. No high-side drive is provided — the output only sinks current, never sources it. ## Supply and temperature boundaries Do not plan to run this part from 3.3 V or from an unregulated 5 V rail that dips below 4.75 V under load.","metaTitle":"SN75453BD Peripheral Driver, 300 mA Sink, 8-SOIC","metaDescription":"Texas Instruments SN75453BD dual peripheral driver with open-collector outputs, 300 mA per channel, 4.75 V to 5.25 V supply, 8-SOIC.","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":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","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-SOIC","Current - Output High, Low":"-, 300mA","Number of Bits per Element":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.99","priceTiers":[{"qty":1,"price":"$0.99000","currency":"USD"},{"qty":10,"price":"$0.86800","currency":"USD"},{"qty":25,"price":"$0.81480","currency":"USD"},{"qty":100,"price":"$0.66510","currency":"USD"},{"qty":250,"price":"$0.61776","currency":"USD"},{"qty":500,"price":"$0.52576","currency":"USD"},{"qty":1000,"price":"$0.42061","currency":"USD"},{"qty":2500,"price":"$0.38118","currency":"USD"},{"qty":5000,"price":"$0.37200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7cc6335c8e9ef2a1672f10cc8b99a71e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN75453BD/alternatives.json"},"ai":{"faq":[{"question":"Can SN75453BD drive a relay?","answer":"Yes. Each output can sink 300 mA, which is sufficient for most 5 V relay coils (typically 50–150 mA). The open-collector output connects the relay coil between an external supply and the driver pin; the driver pulls the output low to energise the coil."},{"question":"Is SN75453BD equivalent to SN75453B?","answer":"The SN75453BD is the surface-mount (8-SOIC) variant of the SN75453B.
