MT88L70ASR MT88L70ANR MT88L70AE1 MT88L70AN1 MT88L70ANR1 MT88L70AS1 MT88L70ASR1 Description The MT88L70 is a complete 3 Volt, DTMF receiver integrating both the bandsplit filter and digital decoder functions. The filter section uses switched capacitor techniques for high and low group filters; the decoder uses digital counting techniques to detect and decode all 16 DTMF tone-pairs into a 4-bit code ...
