It contains three independent non-inverting buffers with open-drain (actually open-drain in LVC nomenclature, sometimes called open-collector) outputs. Each buffer performs the Boolean function Y = A when the output pull-up resistor is present, but the open-drain output only actively drives LOW; it floats (high-impedance) when the input is HIGH. This requires an external pull-up resistor (typically 4.7k-ohm to 10k-ohm) on each output. The open-drain configuration enables three key applications: (1) Level translation - the pull-up resistor can be connected to a voltage different from VCC, translating from 1.8V\/3.3V logic to 5V or other levels; (2) Wired-OR - multiple open-drain outputs can be connected together with a single pull-up, creating a logical AND (active-LOW OR); (3) I2C\/SMBus driving where the bus requires open-drain. The device operates from 1.65V to 5.5V with propagation delay of 3.5ns at 3.3V. The output can sink 24mA at 3.3V. The QDCURQ1 suffix specifies VSSOP-8, AEC-Q100 Grade 1, tape-and-reel.","pin_description":"
