Hello,
I have a question about SN74HC393.

I want a "FUNCTION TABLE including CLK and CLR" and a "timing diagram".

These data are not described in SCLS143D.

These data are described in SCLS457D (data-sheet of SN74LV393A).

Can I use the "FUNCTION TABLE" and the "timing diagram" of SN74LV393A for SN74HC393?

Regards,
Dice-K

The logic diagrams are the same; this implies that you can use the function table and timing diagram for both.

Hi Dice-K ,

Please note active low clk vs active high clock input notation on the pin assignment . the functional diagram seems to be the same , however will have to confirm the same.
