The 100 mA output per channel can drive a 50 Ω or 75 Ω line directly. It runs on a single supply up to 12 V and draws 8 mA quiescent. ## Package and field-service reality It comes in a SOT-23-5 (SC-74A) surface-mount package. That is small enough to fit tight layouts but still hand-solderable with a fine-tip iron — no hot-air station required if you are careful. The pin-1 mark is clear, so orientation is obvious even under a magnifier. No lab bench needed for a swap; a field tech with tweezers, flux, and a soldering iron can replace it on site if the board has accessible pads. MSL 1 out of the bag, so no bake cycle before reflow unless the reel has been open past the floor-life window. ## Lifecycle and sourcing posture It is ROHS3 compliant. No single-source risk here; the part is widely stocked across the channel.","metaTitle":"MAX4178EUK+ Buffer, Current Feedback, 330 MHz, SOT-23-5","metaDescription":"MAX4178EUK+ from Maxim is a 330 MHz current-feedback buffer in SOT-23-5. 1300 V/µs slew rate, 100 mA output, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"MAX4178","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"MAX4178","Package":"Bulk","Slew Rate":"1300V/µs","Mounting Type":"Surface Mount","-3db Bandwidth":"330 MHz","Amplifier Type":"Buffer, Current Feedback","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Current - Supply":"8mA","Number of Circuits":"1","Current - Input Bias":"1 µA","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Input Offset":"500 µV","Supplier Device Package":"SOT-23-5","Current - Output / Channel":"100 mA","Voltage - Supply Span (Max)":"12 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.54","stockQuantity":0,"priceTiers":[{"qty":195,"price":"$1.54000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8f9cc0c51eef9fe822bd36ff87ce632b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the bandwidth of MAX4178EUK+?","answer":"The -3dB bandwidth is 330 MHz, and the slew rate is 1300 V/µs.
