MT3271B General Description

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.
