Need help with a 230IK1 IC (nixie driver)

[ZY]

I got my hands on a few 230IK1 chips and I want to use them for a project as I think they look a bit cooler than the usual K155ID1.

However, I don't know any Russian so reading the datasheets are a bit difficult. So far, I found this website:

http://www.155la3.ru/k230.htm

Halfway down the page, it shows off the 230IK1 IC with a datasheet:

http://www.155la3.ru/datafiles/230ik1.pdf

However it doesn't give much information on which pins provide power. I think K230IK1 is equivalent except for some temperature specs, and I found this datasheet:

http://www.quartz1.com/price/PIC/411N0944515.pdf

Would someone be able to translate for me the pinouts for K230IK1?

I'm assuming pins 49 and 50 are 5V, 24 and 25 are GND, but I want to be sure.

Thanks a bunch!

Hello ZY.

Nice find those chips. I cannot help with a direct translation from Russian, but rather suggest a procedure that has helped me several times with the Russian datasheets: Google Translate on the smartphone (tested on Android).

It lets you point at a text with the smartphone's camera, you highlight the text and it provides a translation almost on the fly. Actually, if you download locally text tiles for the source language it does it live, replacing the original text with the destination language. Amazingly scary to me.

For these highly specialised texts you may need to do a bit of interpretation of some words, but I noticed it is giving better results every time I use it. I usually have it translate into English.

HTH,

Paolo

PS: yes, 49&50 are translated as Supply voltage.

Here's my take on it:

Микросхема представляют собой преобразователь двоичного
кода в десятичный. Корпус типа 421ю50-1.
Назначение выводов: 3 - вход гашения; 5, 13, 15 - вспомогательные
входы; 7, 21 - вход 1 разряда; 9, 19 - вход 8 разряда;
11 - вход 4 разряда; 17 - вход 2 разряда; 23 - вход запятой;
27 - выход Q0; 24, 25 - общие; 29 - выход запятой; 31 - выход Q9;
33 - выход Q8; 35 - выход Q7; 37 - выход Q6; 39 - выход Q5;
41 - выход Q4; 43 - выход Q3; 45 - выход Q2; 47 - выход Q1;
49, 50 - напряжение питания.

Chip is a binary-decimal converter, package type 421Y50-1.

49,50: supply voltage
24,25: common (ground)

7,21: 1 input
17: 2 input
11: 4 input
9, 19: 8 input
3: blanking input
5, 13, 15: auxiliary (mode?) inputs
23: comma input

27: output Q0
47: output Q1
45: output Q2
43: output Q3
41: output Q4
39: output Q5
37: output Q6
35: output Q7
33: output Q8
31: output Q9
29: comma output

Thanks everyone for the help! I can start some tests with this info. I'm going to order a couple 1.25mm pitch FPC connectors from digikey first so I can connect to the IC without soldering to it.

I've been designing IC's for over 30 years now, and this is definitely one of the most unusual I've ever seen. This appears to be from the 1976 to 1980 timeframe, and having to use multiple die to implement such a simple logic function shows that the former USSR was behind in their process technology. Intel's 8080 CPU debuted in 1974 and had 4500 transistors in a single die inside a 40-pin package; the K230IK1 was at most a few hundred transistors and required at least 7 die (maybe more; photo is chopped-off).

A lot of work went into assembling these; I hope you can get some of them running.
