The first time I offered the chips 50 went in two and one half days,  
this second batch of 100 3/4's of them went in 3 days . I was  
recently offered a couple of hundred DTMF chips of various type and I  
now have them in stock and ready to ship. I have data sheets for each  
of the chips, Links to them are on the website. If any one is  
interested in large scale purchase of the 2091's please contact me,  
as it is I have  them offered already with some good quantity discounts.

    150+  - M8870-01/MT8870D DTMF decoders - as a "kit" form with  
crystal, socket, resistors and caps, limit now 6 per order

    100+  - TDK 75T2090 DTMF Transceivers chip in PDIP-18

    300+  - TDK 75T2091 DTMF Transceivers chip in PLCC 28

    60+    - Nat. Semi  TP5088 DTMF Generator Chip ....


I have also begun developing and carrying a line of Arduino  
compatible systems. I just received and have available Arduino  
compatible run time boards for Arduino/ATmega168
