Silicon Systems SSI 201 Integrated DTMF Reciever.  I bought mine
for $5.00 including the crystal and a 22 pin socket.

Outputs in binary (except that Zero is coded 10)
Uses 12V supply and a Color Burst (3.579545 MHz) Crystal.

The application notes even point out how to add pusle dial
detection to the chip.
