Id this ic

[Carrot44]

I have two different IC's that I need to know what they are.

Markings are ND 949576-1110 2618-5G
The other is ND 949576-1100 2617-5G

These date to 86 or so.

Thanks

Ken

What kind of equipment?

 

[Carrot44]

Auto smog control unit for a Toyota corolla

 

[Colt45]

looks like an in-house label to me.

edit: are you going to at least tell us what the package is?

 

[Carrot44]

16 pin dip sorry I figure they are some kind of gates.
This thing works on the princible of if there is a signal say from the throtle switch or o2 sensor a signal is produced to the carb vacuum control module.

Could very well be a PGA, programmable gate arry, which means you can not just go out and buy one.
