Discontinued IC = TMS1121NLL

Hi all,

Can anyone tell me how I can find an 28 pin IC adapter for an old DIP TMS1121NLL Clock timer?

My problem is that I purchased a kit from the UK some 25 years ago and the IC which came with the kit has a pin pitch of approx. 0.4

Length (pin centre to pin centre) = 23mm

Width (pin centre to pin centre) = 11mm

HOWEVER,

The PC board which the TMS1121NLL is supposed to fit into has:

Length (pin centre to pin centre) = 34 mm

Width (pin centre to pin centre) = 16 mm

I tried to have the kit supplier rectify the problem without success, now that I have retired from work it would be nice to complete the project.

What I NEED is the specific pin type descriptio for such an adapter. The ones I have purchased from various suppliers do not fit this IC.

Any help,

Please,

 

Charles
