Where is this information from?If the shift register is used means,while shifting the data all the relays are switching on.
Hi,
If the shift register is used means,while shifting the data all the relays are switching on.

Hi,
may I ask why you .. don´t look for internet circuits.
... and even don´t look into the datasheet. Ok - I agree - this might be boring - but all professionals need to do this, too.
Everything is available. No need to re-invent the wheel.
Even complete projects with code....

In multiplexer ICs both VEE and GND pin are connected to GND supply...
In this case what is the difference between VEE and GND pins...?
If VEE is connected with GND means we can switch negative voltages(-1,-2,-3...,) also..?
If VEE is connected with +5V means only positive signals are switched..?
Hi,
A standard procedure for debugging circuits:
* Measure the HIGH and LOW voltage levels at the HC595 inputs...
* cross check with datasheet whether they comply with the specifications.
