Description

The MT8888C is a monolithic DTMF transceiver with call progress filter. It is fabricated in CMOS technology offering low power consumption and high reliability.The MT8888C utilizes an Intel micro interface, which allows the device to be connected to a number of popular microcontrollers with minimal external logic. The MT8888C-1 is functionally identical to the MT8888C except the receiver is enhanced to accept lower level signals, and also has a specified low signal rejection level.
