HCTR6010A INTEGRATED CIRCUIT

[lionelkjh]

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

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.

Hello; here is the datasheet....

Sounds like a job for an µController. ATmega328 for example, or some flavor of a esp32.

i'll choice ATTiny-xx4(tinyAVR)

Hello; can this integrated circuit be replaced by a MOS circuit from the CD4000 series?

[lionelkjh]

Hello; I looked again on the internet this morning and I don't see any equivalents.....

[Swake]

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? 

[Swake]

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

Good evening; this is the BK PRECISION 820 capacitance meter (here is the manual with its diagram), for which I have to repair; everything can still be found, except this integrated circuit.....

I can't attach it (large file); but it can be found by leaving the eevblog forum....Cdt

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?

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!
