Used to be almost all the 3 1/2 digit DVMS had the Intersil
(now Harris) IC in them. Conversion times were around 100ms.  

Quick check of my Digikey catalog didn't show the 7116?? (not 100%
sure on that number, hence why I went to check).  It does, oddly
enough show a TelCom Semiconductors Inc device listing a TC7116
3 1/2 digit LD chip for $5.85.  Seem to recall Intersil sold them
for about $20, so if it is pin compatible not a bad deal at all!
