From WordNet (r) 3.0 (2006) :

  logic gate
      n 1: a computer circuit with several inputs but only one output
           that can be activated by particular combinations of inputs
           [syn: gate, logic gate]

From The Free On-line Dictionary of Computing (30 December 2018) :

  logic gate
     An integrated circuit or other device whose inputs and
     outputs represent Boolean or binary values as voltages
     ({TTL uses 0V for False or 0, +5V for True or 1).  Different
     gates implement different Boolean functions: AND, OR,
     NAND, NOR (these may take two or more inputs) NOT (one
     input), XOR (two inputs).  NOT, NAND and NOR are often
     constructed from single transistors and the other gates made
     from combinations of these basic ones.  These functions are
     all combinatorial logic functions, i.e. their outputs depend
     only on their inputs and there is no internal state.  Gates
     with state, such as latches and flip-flops, are
     constructed by feeding some of their outputs back to their
