SUMMARY

The discussion focuses on connecting the 74LS166 (Parallel-In/Serial-Out) integrated circuit to a design utilizing the 74LS374 (D-type flip-flops). The key points include that the 74LS166 latches 8 bits of data when the load pin is driven low and requires a clock pulse to shift data to the output. It is emphasized that the 74LS374 may not be necessary if it solely feeds the 74LS166, and users must ensure all data is output before initiating another load.

PREREQUISITES
  • Understanding of 74LS166 operation and control pins
  • Familiarity with 74LS374 D-type flip-flops
  • Knowledge of digital logic design principles
  • Basic experience with clock pulse generation in circuits
NEXT STEPS
  • Research the timing diagrams for the 74LS166 to understand data latching and shifting
  • Learn about interfacing multiple ICs in digital circuits
  • Explore clock pulse generation techniques for synchronous circuits
  • Investigate troubleshooting common issues with parallel and serial data transfer
USEFUL FOR

Electronics engineers, hobbyists designing digital circuits, and students studying integrated circuit applications will benefit from this discussion.

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.
 
thank you very much, that´s the info i needed;)
