TEA1067
Fig.17 Typical applications of the TEA1067 (simplified).
(a) DTMF-Pulse set with CMOS dialling circuit PCD3310.
The dashed lines show an optional flash (register recall by timed loop break).
(b) Pulse dial set with one of the PCD3320 family of CMOS interrupted current-loop dialling circuits.
(c) Dual-standard (pulse and DTMF) feature phone with the PCD3343 CMOS controller and the
PCD3312 CMOS DTMF generator with I2C-bus. Supply is provided by the TEA1081 supply circuit.
