The russians build PDP11's and VAXes. They made chips similar to the
special DEC chips. For example there is an K559IP2 which is an DS8640,
and there is an K559IP1 and they list an DS3881 as equivalent, 4 NAND
gates "standard DEC" Bus driver ..hmm.
1,2-3, 4,5-6 10,11-9 and 13,14-12. ..input,input-output. 16 VCC, 8 GND,
7,15 free. It is an 16 pin 300mil DIP.
Now I have problems to find a Datasheet for an DS3881 which is NOT an
CCFL Inverter from Maxim/Dallas/Analog but I' pretty shure I've seen such
beasts already in the past.
An DEC8881 is sitting next to an DS8640 on a DLV11 I have in my hands..but
this is an DIP14 Chip (similar to an 7401 or an 7439).
What the heck could a DS3881 be?
(DEC Bus drivers are getting rare those days, that's the cause that I've
bought those russian chips in the past for cheap..
