It delivers a maximum propagation delay of 0.74ns, making it suitable for timing-critical signal chains where the comparator's decision time directly sets the system's latency budget. The outputs are differential, available as LVDS or RSPECL levels — the LVDS swing reduces EMI and power on long traces, while RSPECL provides a larger voltage swing for legacy logic families. This dual-output flexibility lets the same comparator drive either a modern FPGA bank or an older ECL-based receiver without a level translator. ## Parametric fit: speed, supply, and temperature With four elements in a single 32-WFQFN exposed-pad package (5x5 mm), the LMH7324SQ/NOPB packs four independent comparators into a compact footprint. The exposed pad aids thermal conduction to the PCB ground plane, critical when all four channels switch at high speed simultaneously. The supply range spans 5 V to 12 V single supply, or ±2.5 V to ±6 V dual supply — this covers standard 5 V and 3.3 V logic rails as well as ±5 V analog supplies. The 80 dB typical CMRR and 75 dB PSRR mean the threshold accuracy holds up against common-mode noise and supply ripple, which matters when the comparator is used in a noisy switching regulator feedback loop. Operating temperature from -40°C to 125°C covers industrial and automotive under-hood environments. The 20.8 mV hysteresis provides clean switching on slow edges without external positive feedback components. Maximum input bias current is 5 µA at 5 V, and maximum input offset voltage is 9.5 mV at 5 V — these are the DC accuracy limits that set the minimum detectable signal. The 7.5 mA maximum quiescent current per channel is modest for a 0.74 ns comparator, keeping the thermal rise manageable in the 5x5 mm QFN.","metaTitle":"Texas Instruments LMH7324SQ/NOPB Quad Comparator, 0.74ns","metaDescription":"LMH7324SQ/NOPB quad high-speed comparator from Texas Instruments. 0.74ns propagation delay, LVDS/RSPECL outputs, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Type":"General Purpose","Package":"Bulk","Hysteresis":"20.8mV","Output Type":"Differential, LVDS, RSPECL","Mounting Type":"Surface Mount","Package / Case":"32-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","CMRR, PSRR (Typ)":"80dB CMRR, 75dB PSRR","Number of Elements":"4","Operating Temperature":"-40°C ~ 125°C","Propagation Delay (Max)":"0.74ns","Supplier Device Package":"32-WQFN (5x5)","Current - Quiescent (Max)":"7.5mA","Current - Input Bias (Max)":"5µA @ 5V","Voltage - Input Offset (Max)":"9.5mV @ 5V","Voltage - Supply, Single/Dual (±)":"5V ~ 12V, ±2.5V ~ 6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.24","stockQuantity":0,"priceTiers":[{"qty":30,"price":"$10.24000","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"How can I get pricing and availability for the LMH7324SQ/NOPB?","answer":"Submit an RFQ through this listing.
