MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145446A/D MC145446A Product Preview Single-Chip 300-Baud Modem with DTMF Transceive.

MC145446A Features

* Single 5 V Power Supply Compatible with CCITT V.21 DTMF Generator and Receiver for All 16 Standard Digits Capable of Driving 0 dBm into a 600 Ω Load (VCC = 5 V) AGC (Auto Gain Control) Ampl

MC145446A Applications

* of any voltage higher than the 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 inputs are tied to an appropriate logic voltage level (
