Hi,
        I've got a small little doubt about the outputs of
        74HC164. Are the outputs of these ICs totem pole ?
        In other words, Does the IC pull down the output to
        ground when one of its outputs is low ?

        I have designed a moving message display with a 74HC238
        Multiplexer and a few 74HC164s. But out here, 238s are
        not available. So, I have to use 74HC138 which is the
        same as 238 but with inverted outputs. If the 164 can pull
        its output pin low (like a PIC), this problem could be solved
        with a small change in the PIC software.

Thanks,

Jeethu Rao
