content: Hello; I am looking for the following integrated circuit: HCTR 6010A (DIP-16), or an equivalent that could be close to it because it is old.... Could someone help me?? Thank you in advance

content: Can you post the datasheet?The only links I could find to it are from the Datasheet Archive, but that site is a little too much of a security risk for me to download anything from it.

content: If you find an equivalent it will be of the same era and have the same availability issues. What is this counter chip used for?

content: If it is an important instrument you want to restore then going the arduino route (or something equivalent) is probably the most realistic way.

content: That chip is a counter. It counts 'time'. This time comes from pen 3 of a NAND port in IC203. I don't have the name of IC203 but I think it is a common 4093.The count is interrupted at the moment that it represents the measurement, I think this comes from pen 4 of IC203. It resets and the cycle is restarted.With a means to visualise these 2 signals (scope, frequency counter) you might want to experiment and build some emulator that can replace the HCT6010A. How far you want to go will depend on the (sentimental) value this BKP 820 has for you.btw: Are you're certain that the HCT6010A is dead and not something else?

content: Hello; most of the integrated circuits will need to be replaced because this device was the victim of a capacitor charged by its previous owner, (except the HCTR6010) because I need to test it.......Thanks for your research!

content: Hello everyone! The integrated circuits having arrived; I was able to get to work, and I am making progress on its arrival! The voltages and various signals are present; but I have no display.....I strongly suspect the integrated circuit HCTR6010 controlling the voltage of the displays to be blown because the signals enter but do not leave the IC....The only downside; I cannot find out if this integrated circuit is still manufactured and I do not know if we can find an equivalent.....Its reference is: IC102... See the P15 diagram that I attached.....Could someone help me?? Thanks in advance

content: you have some B&K 820 and 830 on sale on ebay ... the prices will not be in a range that you'll appreciate ...in the end you would need to mimick this chip, while decoding encoding to display the read values ...best advise would be: put it aside and wait if some in your country will appear overtime ....

content: hello Lionelkjh,Very few/faint matches, even by obsolete IC sellers :https://www.afrenterprises.com/partno-search?searchby=partno&searchkey=HCTR6010https://www.utsource.net/sch/HC6010-0-D-000.htmlhttps://www.afrenterprises.com/partno-search?searchby=partno&searchkey=hctr6010Probably no stock, but you can still try to contact them.IC propagation is really slow (1,5 µs typical) so a replacement by a rather recent µC or a vintage CPLD, put on a piggy-back PCB might be the best solution to replace the defective part.Voltage compatibility has to be checked for the dedicated BK PRECISION 820 because the genuine part accepts up to 10 VDC.Update #1The IC102 (HC6010) is powered by a 10,3 VDC supplySo a functional replacement needs also to cope with this higher voltage.VDD on IC103 is 4.4 to 6VDC (4 'C' cells in series)

content: Hi Lionel, my two cents ... Your best bet is to find a genuine HCTR6010, but only from trusted souces (not eBay, obviously, known for their fakesnor Utsource - they sell fakes too, I experienced that with a RAM where reference does not match pinout). Anyway, you can still redesign the IC:Do not use CPLDs, due to their high power consumptionAn Arduino obviously cannot be used (size, power consumption)74C926 or the like do not work either (missing overflow, 6V for max. VCC). And so does the MC14499The best would be to use either a microntroller (a 18 pin PIC?) in TSSOP package on a PCB with a voltage regulator and level shifters, or perhaps, rebuild a counter in CMOS technology with small IC packages (SOIC, SSOP or TSSOP), knowing that you have 'plenty of' room at the left of IC102 to IC104. You can even design a small board replacing IC102 and 104 together, giving you extra room for logic 'glue'.And yes, you can have donors from the internet. I just purchased an AOIP 5901 (same meter rebranded by AOIP) for 30€ on Leboncoin, in a museum condition (I quote Leboncoin since you're French too). But anyway, redesign of vintage components is often the best way to go. I'm redesigning right now a Signetics 8T26 (used in Tektronix 500 series), using an ATF16V8BQL and an ULN2003 is TSSOP cases, to fit the original IC size. And with the help of JLC or the like, it's easy and cheap to redesign multilayer boards.I hope it helps!Bon courage !

content: Sure that redesigning the chip would solve the 'unobtainum' issue and also the hassle created buy buying fake parts.IMO, In this particular case, the power consumption is not really an issue : the TE is only used for short periods of time and 'C' cells have rather large energy capacity.By the way, it would be interesting to launch a thread that lists all the work done in redesigning obsolete parts.If such a topic does not yet exist, I'll create it on this forum.Two exemples :Tektronix or MAXIM '155-0241-02' horizontal output stage : U800 on the TEK 2465/2467B oscilloscopes.Replacement designby Thomas Lafay.Video 'Tektronix 2467B U800 failure'HEF40244'Octal buffers with 3-state outputs' in DIL package for 'Datron Wavetek 1281' metrology grade voltmeterHowever, an SMD packaged version isavailable
