That places it in the class of comparators used for time-of-flight measurements, high-speed line receivers, and pulse-width discriminator front-ends where a few hundred picoseconds of skew can flip a bit. The 375 ps figure is the max over temperature and supply, not a typical — the 20-PLCC package adds about 50 ps of trace delay per side from the bond wire, so factor that into your timing budget if the output drives a distant line. ## ECL outputs — termination is not optional The output type is complementary, differential, ECL, open-emitter. That means the outputs are emitter-follower stages that need a pull-down resistor to the negative supply rail (typically -2 V or ground-referenced with a Thevenin termination). No internal pull-up exists — leave the emitter open and the output floats high. The 30 mA typical output current drives 50 Ω loads into -2 V cleanly. If your design expects a TTL or LVCMOS level, this part requires a translator or a PECL termination network to shift the levels. The latch input holds the state on the rising edge of the latch-enable pin; leave it unconnected or tie high for transparent mode. ## Supply rails and quiescent budget The quiescent current splits into two rails: 18 mA on one, 80 mA on the other (the ECL output stage draws the larger share). Total around 98 mA worst-case, which is modest for a dual 375 ps comparator but not a low-power part. The ±1 mV hysteresis is built in, so you do not need external positive feedback resistors to clean up noisy edges. Input offset voltage maxes at 6 mV at 5 V supply, and input bias current at 40 µA — both typical for a high-speed bipolar comparator. CMRR is 69 dB typical. ## Package and rework profile The 20-PLCC (J-lead) package is a known quantity — no BGA reball or hot-air profile guesswork. The leads are on the perimeter, visible for inspection, and the J-lead form is forgiving of board flex. The 9x9 mm body in the supplier device package field matches the industry-standard PLCC-20 footprint. The mounting type is surface mount, and the shipping medium is tube, not tape and reel.","metaTitle":"ADCMP565BPZ dual comparator with latch","metaDescription":"ADI ADCMP565BPZ dual ultra-fast comparator with latch. 375 ps prop delay, ±1 mV hysteresis, ECL outputs, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"with Latch","Package":"Tube","Hysteresis":"±1mV","Output Type":"Complementary, Differential, ECL, Open-Emitter","Mounting Type":"Surface Mount","Package / Case":"20-LCC (J-Lead)","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"69dB CMRR","Number of Elements":"2","Operating Temperature":"-40°C ~ 85°C","Current - Output (Typ)":"30mA","Propagation Delay (Max)":"0.375ns","Supplier Device Package":"20-PLCC (9x9)","Current - Quiescent (Max)":"18mA, 80mA","Current - Input Bias (Max)":"40µA @ 5V","Voltage - Input Offset (Max)":"6mV @ 5V","Voltage - Supply, Single/Dual (±)":"±4.75V ~ 5.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.23","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$16.23000","currency":"USD"},{"qty":10,"price":"$14.91400","currency":"USD"},{"qty":25,"price":"$14.29560","currency":"USD"},{"qty":100,"price":"$12.59570","currency":"USD"},{"qty":250,"price":"$11.97748","currency":"USD"},{"qty":500,"price":"$11.20472","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADCMP565.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the propagation delay of the ADCMP565BPZ?","answer":"The maximum propagation delay is 0.375 ns (375 ps) over temperature and supply.
