I need help designing a circuit that will latch on to the carrier detect signal of a 232 circuit. The new circuit must hold the signal for 1.5 seconds. Here is the kicker. I need the logic levels of the input and output to be the same (i.e. input = high, output must be high; input goes low, the output goes low and hold for 1.5 seconds).
I was thinking of using a 555 or 556 timer. Can anyone help with this project.
Thanks in advance.
