Quad general-purpose comparator, 28ns max propagation delay, 4mV internal hysteresis, push-pull rail-to-rail outputs, 2.7V to 5.5V supply, -40°C to +85°C, 16-QSOP package.","salesMarkdown":"## Quad general-purpose comparator with 28 ns propagation delay The Maxim Integrated MAX978EEE+ is a quad general-purpose comparator in a 16-QSOP package, built for signal threshold detection and level translation in industrial and mixed-signal systems. Each of the four comparators includes 4 mV of internal hysteresis, which eliminates output chatter near the trip point without external positive feedback resistors — a clean one-chip solution for zero-crossing detectors, window comparators, and over-voltage/under-voltage monitors. The push-pull, rail-to-rail output stage drives CMOS logic inputs directly; no pull-up resistor is needed, which saves a component per channel and simplifies the board layout. Propagation delay is 28 ns maximum, fast enough for switching power-supply fault latches and sensor thresholding at moderate frequencies, though not intended for GHz-level clock recovery or RF envelope detection. Supply range is 2.7 V to 5.5 V single supply, covering 3.3 V and 5 V logic rails. Quiescent current is 650 µA maximum across all four channels, so the total power budget stays under 3.6 mW at 5.5 V — low enough for always-on monitoring in battery-backed equipment. The part operates over the industrial temperature range of -40°C to +85°C, suiting it for outdoor telecom cabinets, factory-floor PLCs, and engine-bay sensor interfaces that see thermal cycling. ## 95 dB CMRR and 100 dB PSRR — noise rejection in mixed-signal environments Common-mode rejection ratio is 95 dB typical, and power-supply rejection ratio is 100 dB typical. These figures mean the comparator's trip point shifts less than 20 µV per volt of supply ripple or common-mode input variation — important when the comparator shares a rail with a switching regulator or sits on a long sensor cable that picks up ground noise. Input offset voltage is 2 mV maximum at 5 V, and input bias current is 0.075 µA maximum at 5.5 V. The low bias current allows the use of high-impedance sensor dividers without loading the source, and the offset is tight enough for 1% threshold accuracy with a 200 mV reference. ## Active lifecycle — no end-of-life risk for current designs The MAX978EEE+ carries an Active product status and is ROHS3 compliant. There is no last-time-buy notice or obsolescence risk on the horizon, so this part can be specified into new production builds without worrying about a forced redesign mid-cycle. Surface-mount assembly on the 16-SSOP (0.154\", 3.90 mm width) footprint is standard — no exotic soldering profile needed. The supplier device package is 16-QSOP, which is the same body size and pinout as the SSOP-16; the two designations refer to the same physical package from different suppliers.","metaTitle":"MAX978EEE+ Quad Comparator, 28ns, 4mV Hysteresis, 16-QSOP","metaDescription":"MAX978EEE+ quad general-purpose comparator from Maxim Integrated. 28ns propagation delay, 4mV internal hysteresis, rail-to-rail push-pull outputs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"General Purpose","Package":"Tube","Hysteresis":"4mV","Output Type":"Push-Pull, Rail-to-Rail","Mounting Type":"Surface Mount","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"95dB CMRR, 100dB PSRR","Number of Elements":"4","Operating Temperature":"-40°C ~ 85°C","Propagation Delay (Max)":"28ns","Supplier Device Package":"16-QSOP","Current - Quiescent (Max)":"650µA","Current - Input Bias (Max)":"0.075µA @ 5.5V","Voltage - Input Offset (Max)":"2mV @ 5V","Voltage - Supply, Single/Dual (±)":"2.7V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.38","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.38000","currency":"USD"},{"qty":10,"price":"$9.38100","currency":"USD"},{"qty":25,"price":"$8.94440","currency":"USD"},{"qty":100,"price":"$7.76650","currency":"USD"},{"qty":250,"price":"$7.41744","currency":"USD"},{"qty":500,"price":"$6.76296","currency":"USD"},{"qty":1000,"price":"$5.89032","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/44df2a8fd52084a7bc23989f076445e4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX978EEE+ obsolete or active?","answer":"The MAX978EEE+ is Active with no last-time-buy or discontinuation notice.
