Hi all,
I've got a dead 1820-0090 IC from an 5216A counter and am looking for
a common replacement if it exists.
Its function is "buffer storage" and it sits between a decade counter
& a decoder driver chip.
In my search I came across
which has heaps of HP semicond/IC cross reference data but
unfortunately doesn't include the 1820-0090.
Cheers
