HM9270D RECEIVER Datasheet PDFDTMF RECEIVER DTMF RECEIVER |
Part Number | HM9270D |
---|---|
Description | DTMF RECEIVER |
Feature | HM 9270C/D DTMF RECEIVER
General Descri ption
The HM 9270C/D is a complete DTMF receiver integrating both the bandspli t filter and digital decoder functions. The filter section uses switched capac itor techniques for high- and low-group filters and dial-tone rejection. Digit al counting techniques are employed in the decoder to detect and decode all 16 DTMF tonepairs into a 4-bit code. Exte rnal component count is minimized by on -chip provision of a differential input amplifier, clock-oscillator and latche d 3-state bus interface. Features • • • • • • • • Complete re ceiver in an 18-pin package. E . |
