HT9212D=HM9212D /DIP-24W

DTMF приймач

The HT9212D/HM9270C/D is a complete DTMF receiver integrating both the bandsplit filter and digital decoderfunctions. The filter section uses switched capacitor techniques for high- and low-group filters and dial-tonerejection. Digital counting techniques are employed in the decoder to detect and decode all 16  DTMF tone-pairs into a 4-bit code. External component count is minimized by  on-chip provision of a differential  inputamplifier, clock-oscillator and latched 3-state bus interface
