Are you really asking for the part numbers for most, but not all, of the Integrated Circuits on an S5 hash board? If you have a board you can read them off? Give us a bit of background, why you want this information?

The main part you are likely to need when repairing is the Hash ASIC BM1384, (U4 - U47). These would only be available from Bitmain, however I suspect they are not selling them, so you will need to remove devices from a failed board to repair others.

Yes sorry my mistake, U6, U9, U12 ..... U39, U42, U45 are as you say SN74LVC1G07 The rest of the chips in the Range U4 - U47 are the BM1384

You are 100% about chips numbers ...
And thanks for confirm the SN74LVC1G07

Also step up U101 was founded by other user ( looks 100% exact part), take a look and let me know, here the link

Here,s my best shot at a complete list of IC's on the Hash Board in the S5.

U1 - LM75A - Digital temperature sensor.
U3,U52,U53,U54,U55,U56,U57,U58,U59,U60,U61,U62,U63,U64 - C07F - SN74LVC1G07 - Buffer/Driver Open-Drain Output.
U6,U9,U12,U15,U18,U21,U24,U27,U30,U33,U36,U39 - 4VK4 - LN1134 - 1.85V LDO regulator.
U42,U45,U48 - R18 - SPX5205M5-L-1-8  - 1.8V LDO regulator.
U4,U5,U7,U8,U10,U11,U13,U14,U16,U17,U19,U20,U22,U24,U25,U26,U18,U29,U31,U31,U34,U35,U37,U38,U40,U41,U43,U44,U46,U47 - BM1384 - Hash ASIC.
U101 - 0J - RT8537 - Current mode Boost-type LED driver.


Notes :-

The SN74LVC1G07 Buffer chips are not fitted to the V1.1
The LDO's, except for the last stage are not fitted to V1.91
The R18 LDO regulators fitted to the last 3 stages are different than those fitted to the first 12, They are fed with the 14V from U101 as opposed to being fed from the Core Voltage 3 levels up for the preceding 12.

U42-45-48 are "R18", I think.
That'd be Exar reference SPX5205M5-L-1-8

Yes R18 looks good. I had been looking for IR18... Have corrected my list. I guess that covers it for the IC's  Smiley
