   latch
      A digital logic circuit used to store one or more bits.  A
      latch has a data input, a clock input and an output.  When the
      clock input is active, data on the input is "latched" or
      stored and transfered to the output either immediately or when
      the clock input goes inactive.  The output will then retain
      its value until the clock goes active again.
