Responding to: ???'s previous message
Santosh Kumar Jena said:
i am not getting you . what will happen when we the give input as a high or low to both drivers ?

What will happen when you have a driver that shorts to ground (sinks current)?
What will happen when you have a driver that shorts to the supply voltage (sources current)?

As already asked - what datasheets did you make use of that does not contain enough information for you to notice the big difference between the two drivers?

                           None of this makes sense!            01/01/70 00:00      
                           It appears you need latching relays            01/01/70 00:00      
                              Latching relay is still slow            01/01/70 00:00      
                                 You're right, but the relay spec's should reveal that            01/01/70 00:00

                                 use toggle types ... they were around once ...            01/01/70 00:00      
                                    SPI + latched shift registers are good choices            01/01/70 00:00      
                                       The protocol is good ... but not necesary here            01/01/70 00:00      
                                          SPI is excellent for driving long shift registers            01/01/70 00:00      
                                             tell us, Per, what data types does SPI support?            01/01/70 00:00
