Description

The ML7070-01TB is a multi-functional DTMF transceiver LSI with built-in a DTMF signal generator, a DTMF signal receiver, a call progress tone generator, a call progress tone detector, and a FAX (FX) signal detector. It has a wide range of power supply voltage from +2.7 V to +5.5 V and low power consumption. The 4-bit processor interface supports both the Intel processor mode and the Motorola processor mode. The DTMF receiver can select either the high-speed detection mode or the normal detection mode. It also has a built-in call progress tone generator, FAX signal detector, and a 3.579545 MHz crystal oscillator circuit. The package includes a 32-pin plastic SSOP.
