It takes a 4-bit Binary-Coded Decimal (BCD) input and activates one of ten open-collector outputs corresponding to the decimal digit (0–9). It is commonly used in digital logic circuits for display driving, lamp driving, and relay switching.\u003c\/p\u003e\n\u003ch4\u003eQ: What package type is the SN74LS145DR and is it suitable for surface-mount assembly?\u003c\/h4\u003e\n\u003cp\u003eA: The SN74LS145DR comes in a SOIC-16 (Small Outline Integrated Circuit, 16-pin) surface-mount package, making it well suited for PCB surface-mount assembly, compact designs, and modern electronic prototyping projects.\u003c\/p\u003e\n\u003ch4\u003eQ: How many units are included in this listing?\u003c\/h4\u003e\n\u003cp\u003eA: This listing includes 5 pieces of the SN74LS145DR (74LS145) SOIC-16 integrated circuit, all in new condition — great value for prototyping, spare stock, or small production runs.\u003c\/p\u003e\n\u003ch4\u003eQ: What logic family does the 74LS145 belong to, and what supply voltage does it require?\u003c\/h4\u003e\n\u003cp\u003eA: The 74LS145 belongs to the 74LS (Low-Power Schottky TTL) logic family. It operates at a standard 5V TTL supply voltage (4.75V to 5.25V), making it compatible with most classic and modern 5V digital logic systems.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does the SN74LS145DR (74LS145) integrated circuit do?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The SN74LS145DR is a BCD-to-Decimal decoder\/driver IC.
