D951-1 device ID
These are ceramic 14 pin devices with what looks like a 1969 date code on them.
Does anyone know what they are? |

Re: D951-1 device ID
Anglo–American Microelectronics Data 1968–69 D951
D951 gated monostable multivibrator If you use the first line of this post as the search term, it should give you a Google books hit that will give you the datasheet (page 171 of vol1). Last edited by Terry_VK5TM; 19th Jul 2018 at 4:59 am. |

Re: D951-1 device ID
My first guess is that they are DTL monostable multibrators. I have an old Motorola databook that lists the 951 as that, and one package for it was 14 pin DIL.

Re: D951-1 device ID
That is useful.
I now need to find out what the pin out is and then I can use some of them. I have got a drawer full of them that has been there for 30 years after sorting them out from a goody bag all those years ago. So as the data books are expensive I am going to have to put it on a conductive plate and find the substrate pin with a capacitance bridge and then see where I can go from there. |

Re: D951-1 device ID
Pinout for the D951 can be seen in google books.

Re: D951-1 device ID
I have just had a quick look.
Have you got a link to the pin out? |
