Dual Tone Multiple Frequency Line Interface

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 General Description

TxA1 Non *Inverting Analog Output (Pin 1) This pin is the line driver non *inverting output. A + 7 dBm (typ) differential output voltage can be obtained by connecting a 1.2 kΩ load resistor between TxA1 and TxA2. Note that the DSI input, if used, must be controlled for the output leve.
