Hi,

i am trying to connect the IC 74LS166 (Parallel in / Serial out) to my design, but i´m having trouble connecting this component, if anyone knows how this is done or any idea i would appreciate it.

i have the parallel intput from a 74LS374 which has 8 D-type flip-flops, basically i just need help connecting the control pins


thanks in advance

If all the LS374 is doing is feeding the LS166 then you probably don't need it.
The 166 will latch 8 bits of data when you drive the load pin low.
The only other thing you need is a clock pulse to shift the data to the output port.
Of course you do need to wait until all the data is written out before doing another load.
