That part is used in several early 7000-series time bases.
7B50A and 7B53A are examples. A while ago, while still available, these
plugins could be had for a few $$.
Thanks for the info - i may even buy a whole timebase to part out in the
worst case.
You may want to check the circuits around the IC before replacing because
it could be the victim of a failure, not the source.
Yes, i will be sure the surrounding circuits are perfect before plugging in
new. Thanks!
