I need a quantity (up to 100 pieces) of a Holtek DTMF dialler chip but their UK distributor has just informed me that they have now ceased production of all dedicated dialler chips.
Before considering approaching any of the various (rather dubious and mainly Far-Eastern) parts-finder services being offered on-line I thought I'd ask in this NG just in case anyone has any surplus stock of either of the following devices:-
HT9305A-18DIP or the rather older HT9315A-18DIP
Alternatively, can anyone recommend a trustworthy parts-finder company, preferably in the UK, that may be worth contacting.
TIA - Dave.
