Product Summary

The MT3370BS is a Wide Dynamic Range DTMF Receiver. It incorporates an AGC for wide dynamic range and are suitable for end-to-end signalling. The MT3370BS provides an early steering (ESt) logic output to indicate the detection of a DTMF signal and requires external software guard time to validate the DTMF digit. The MT3370BS is used in Integrated telephone answering machine, End-to-end signalling, Fax Machines.

Parametrics

MT3370BS absolute maximum ratings: (1)DC Power Supply Voltage VDD-VSS: 6 V; (2)Voltage on any pin (other than supply) VI/O: -0.3 to 6.3 V; (3)Current at any pin (other than supply) II/O: 10 mA; (4)Storage temperature TS: -65 to 150 ℃; (5)Package power dissipation PD: 500 mW.
