MT3271B, MT3370B, Wide Dynamic Range DTMF Receiver

Data Sheet The MT3x7xB is a family of high performance DTMF receivers which decode all 16 tone pairs into a 4-bit binary code.

These devices incorporate an AGC for wide dynamic range and are suitable for end-to-end signalling.

The MT3x70B provides an early steering (ESt) logic output to indicate t

MT3271B Features

* Wide dynamic range (50 dB) DTMF Receiver Call progress (CP) detection via cadence indication 4-bit synchronous serial data output Software controlled guard time for MT3x70B Internal guard time circuitry for MT3
