Hi!

I have a system based on 89c51. this system includes 6116 & address, data demultiplexed using 74hc373.
Port 1 is engaged for driving a set of 8 LEDs.
Now I want to interface 74HC574 so that I can use its output to drive the 8 relays.
Can anybody suggest the interface?

I tried connecting data bus to the 74hc574 input & WR/ through the invertor was given to clk pin(11) & address decoder (74hc138) pin 14 was connected to oc/ pin (1).
This has not worked.
please help me out.

Thanks
