I finally figured out what I needed yesterday. it was a flip flop chip.
because an input of 1 to it will cause it to continue to output a 1 even
though the 1 was applied to the input for a fraction of a second. this is
similar to what happens when the gate of an SCR is supplied a positive
voltage. it continues to conduct.
