At 2.7 V supply the delay stretches slightly; at 5.5 V it tightens. For a 1 MHz PWM current-sense loop, the 40 ns delay adds about 14 degrees of phase lag at the crossover — enough to push a Type-III compensator toward instability if the zero placement isn't backed off. The 1.5 mV internal hysteresis cleans up chatter on slow edges without external positive feedback. Quiescent current maxes at 300 µA per device — the quad draws under 1.2 mA total, which keeps the thermal rise in the TSSOP negligible even at 85°C ambient. The push-pull output swings rail-to-rail without a pull-up resistor, saving a component on the BOM.","metaTitle":"MAX9144EUD+T Quad Comparator, 40ns, 14-TSSOP, Active","metaDescription":"MAX9144EUD+T quad general-purpose comparator, 40ns propagation delay, 1.5mV hysteresis, push-pull output, 14-TSSOP, RoHS3 compliant, active production, order","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"General Purpose","Package":"Tape & Reel (TR); Cut Tape (CT)","Hysteresis":"1.5mV","Output Type":"CMOS, Push-Pull, TTL","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"81.94dB CMRR, 81.94dB PSRR","Number of Elements":"4","Operating Temperature":"-40°C ~ 85°C","Propagation Delay (Max)":"40ns","Supplier Device Package":"14-TSSOP","Current - Quiescent (Max)":"300µA","Current - Input Bias (Max)":"0.32µA @ 5V","Voltage - Input Offset (Max)":"2mV @ 5V","Voltage - Supply, Single/Dual (±)":"2.7V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.67","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.67000","currency":"USD"},{"qty":10,"price":"$5.09600","currency":"USD"},{"qty":25,"price":"$4.81760","currency":"USD"},{"qty":100,"price":"$4.17530","currency":"USD"},{"qty":250,"price":"$3.96120","currency":"USD"},{"qty":500,"price":"$3.55440","currency":"USD"},{"qty":1000,"price":"$2.99768","currency":"USD"},{"qty":2500,"price":"$2.84780","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is MAX9144EUD+T's propagation delay and how does it affect circuit design?","answer":"The MAX9144EUD+T has a maximum propagation delay of 40 ns.
