Its output stage supports CMOS, MOS, open-drain, and TTL logic families, making it straightforward to interface with 3.3V or 5V controllers or wired-OR buses without external level shifters. ## Last Buy — secure inventory now This means the manufacturer has announced end-of-life, and the final purchasing window is open. Buyers should commit to their lifetime requirement quantities promptly to avoid supply gaps. For ongoing designs, consider evaluating the active LM393 series variants in the same 8-VSSOP footprint, verifying pin compatibility and parametric alignment. ## 8-VSSOP footprint — layout notes Housed in an 8-VSSOP package (0.118-inch body width, 3.00mm width, 0.65mm pitch), this part suits space-constrained PCBs. ## Key parametric limits for design margin Maximum input offset voltage is 2mV at 30V supply, and maximum input bias current is 0.25µA at 5V. These figures set the floor for threshold accuracy in low-signal applications such as battery monitors or sensor comparators. Quiescent current maxes at 2.5mA per device, and each output can sink 20mA typical — enough to drive an LED or optocoupler directly, but not a relay coil without a buffer transistor.","metaTitle":"TI LM393ADGKRG4 Dual Differential Comparator, 2V-36V","metaDescription":"Texas Instruments LM393ADGKRG4 dual differential comparator. 2V to 36V supply, 2mV max offset at 30V, 0°C to 70°C.
