Part Number: DS3668 Hello,
What is the difference between DS3658 and DS3668? Why does DS3668 draw more current than DS3658? Is there an alternative to DS3658? Thank you.
Best regards, Thanh
Part Number: DS3668 Other Parts Discussed in Thread: SN75451B The DS3668 quad fault protect driver comes in a through-hole packaging. Is there a replacement with a surface-mount package? Thanks.
Part Number: SN75451B Other Parts Discussed in Thread: SN65472-EP , DS3668 Hi,
Our application is to provide driving current to the sending optical module of AVAGO. The recommended device in the datasheet is SN75451.
SN75451 can meet RoHS, but the…
Dear Shreyas,
Thank you for your response. In the interim I found the TI part DS3668. This seems to be a Quad driver but I am not sure what the resistance of the open collector to ground will be compare to the 75453.
Do you think operation using the…
Hi Puspam,
Does DS3668 or SN75437A work? There aren't any 4-channel parts that have directly the same setup as the ULN parts. There's also ULN2003A which has 7 channels.
Thanks,
Patrick
Seema,
LM321 is not a good choice. I suggest these alternatives in order.
TLV1805, TLV1805-Q1 Comparators (not for high output current )
L293D Quadruple Half-H Drivers (needs a 5V supply, too)
DS3668 Quad Fault Protected Peripheral Driver (needs…
