I am trying to identify this chip by RS - It has their part number
(307-070) but it does not appear in their catalogue or on their web
site and they cannot tell me what it is! The part no. is clear and
that it is actually an RS device is also evident by their logo... Has
anyone an old catalogue, perhaps from about 1990 or can anyone tell me
what this device is? Any help would be much appreciated...
Thanks... Richard.

** Google tells me it is a frequency to voltage converter.

Just search on " RS 307-070 "

If you describe the pack, that might narrow it right down.

My 1990 RS catalogue tells me that it's a TSC9400CJ V to F or F to V
converter by Teledyne Semiconductor. It operates over the range from
10Hz to 100kHz. I have the pinout and some minor specs, but that's it.

I can scan the catalogue page if you need it.

Similar parts are TSC9401CJ and TSC9402CJ, the difference being in
tempco and linearity.

Page 10 of the Computer Journal / Issue #28 has an A/D converter
circuit built around this chip:

9400CJ , datasheet number 3021
While at it , anyone know of a browsable Radio Spares catalogue out there
for the 50s / 60s or 70 s ?
Googling " 1963 radio spares catalogue" and similar got nowhere

I cannot find my bookmark of the 1950s USA component catalogues that someone
scanned in and placed out there, can anyone point me to the name at least of
the company

For the last bookmark was there , I thought it was something other than
