CMOS or BiCMOS logic gates process input signals with propagation delays specified per the logic family. Input hysteresis (on Schmitt-trigger variants) improves noise immunity. Partial power-down Ioff circuitry prevents backflow current when the device is powered down. Direction control and output enable pins manage bus arbitration in multi-master systems.","pin_description":"
