Its 20ns typical rise and fall time means the gate charges fast enough to keep switching losses low in a 100-500 kHz SMPS or motor-drive stage, but the 8-DIP package limits the layout to through-hole prototyping or low-volume production runs. The inverting input flips the logic sense — a high on the input turns the output low, and vice versa — which matters when the PWM controller output polarity does not match the power-stage topology. Supply voltage spans 4V to 15V, covering 5V and 12V bias rails commonly found in industrial control panels and telecom bricks. Logic thresholds are 1.1V (VIL) and 2.7V (VIH), so a 3.3V or 5V microcontroller output drives it directly without a level shifter. The 8-PDIP through-hole package with 0.300\" (7.62mm) body width is a standard DIP footprint — no fine-pitch alignment, no moisture sensitivity level concern on the line. Supplied in tube, which is the typical carrier for through-hole parts; the tube quantity matches standard DIP-8 pick-and-place feeder tubes if your EMS supports tube-fed insertion.","metaTitle":"UCC27321P Texas Instruments Low-Side 9A 8-PDIP","metaDescription":"Texas Instruments UCC27321P low-side gate driver: 9A peak source/sink, 20ns rise/fall, 4V-15V supply, inverting input, 8-PDIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Gate Type":"N-Channel, P-Channel MOSFET","Input Type":"Inverting","Channel Type":"Single","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4V ~ 15V","Number of Drivers":"1","Base Product Number":"UCC27321","Driven Configuration":"Low-Side","Operating Temperature":"-40°C~105°C(TA)","Rise / Fall Time (Typ)":"20ns, 20ns","Supplier Device Package":"8-PDIP","Logic Voltage - VIL, VIH":"1.1V, 2.7V","Current - Peak Output (Source, Sink)":"9A, 9A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3300","priceTiers":[{"qty":1,"price":"$2.33000","currency":"USD"},{"qty":10,"price":"$2.09000","currency":"USD"},{"qty":25,"price":"$1.97160","currency":"USD"},{"qty":100,"price":"$1.67980","currency":"USD"},{"qty":250,"price":"$1.57728","currency":"USD"},{"qty":500,"price":"$1.38012","currency":"USD"},{"qty":1000,"price":"$1.14353","currency":"USD"},{"qty":2500,"price":"$1.11600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/20b75c5251e8591bc685c5db0fca715d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/UCC27321P/alternatives.json"},"ai":{"faq":[{"question":"Can UCC27321P replace UCC27322?","answer":"The UCC27322 is a non-inverting version of the same driver. The UCC27321P has an inverting input, so the logic sense flips. If your controller output polarity matches the non-inverting variant, swapping in the UCC27321P would require a firmware or external inverter change. No direct pin-compatible drop-in."},{"question":"Is UCC27321P compatible with 5V logic?","answer":"Yes — the VIH threshold is 2.7V, so a 5V CMOS or TTL output drives it cleanly. The VIL of 1.1V also works with 3.3V logic, but confirm the controller's output low voltage stays below 1.1V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/UCC27321P","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/UCC27321P when reusing this data.
