pp732-734 is 3 pages of what I mentioned re the 8881
http://bitsavers.org/pdf/dec/qbus/Chipkit_Users_Manual_1982.pdf related but not 8881 -
lots of handy IC descriptions
http://www.bitsavers.org/pdf/dec/internal/Semiconductor_Handbook_V1_1987.pdf all you want
to know about the DCxxx ICs and more modern stuff
http://w.datasheets.pl/elementy_czynne/IC/8881.pdf "DEC" 8881 ?
What I could rummage tonight

Subject: [cctalk] Q about DS3881, N8881 DEC8881..
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..
Regards,
Holm
