source for CA3161 (or NTE2032)

[Alex [Temple-Heath List]]

I wanted to thank everybody that responded on and off list to my 
query. I resolved the situation by using an old NTE8374 that I 
happened to have in one of my junk box drawers. It's also a 
discontinued chip but its an almost direct plug-in replacement for 
the CA3161. Just had to set the proper levels at pins 3 and 4, and it 
worked just fine. Difference is this one supplies just 15mA (instead 
of 25mA for the CA3161), but everything seems to be working fine now.

BTW, earlier I also managed to get the circuit working by using an 
outboard 4511 decoder/driver on a breadboard, but it needed a few 
additional parts (transistors/resistors) for the conversion to work, 
and also the display would had to be changed to a common cathode 
type. So it wasn't as elegant a solution as the NTE8374, but still 
doable. The suggested 7447 TTL chip substitution would of course also 
be a good option.

Thanks again.
