MC145740 Features

* Single Power Supply: 3.6 to 5.5 V DTMF Generator and Receiver for All 16 Standard Digits 0 dBm Line Driver Into 600 Ω Load AGC Amplifier Programmable Transmit Attenuator Serial Control Interface Power Down Mode, Less Than 1 µA 2

MC145740 Applications

* of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation, it is recommended that Vin and Vout be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Reliability of operation is enhanced if unused logic inputs are tied to an appropriate logic voltage leve
