Overview: TECHNICAL DATA IN9270 DTMF RECEIVER High-Performance Silicon-Gate CMOS The IN9270 is a plete DTMF receiver integrating both the bandsplit filter and digital decoder functions. The filter section uses switched capacitor techniques for high- and low-group filters and dialtone rejection. Digital counting techniques are employed in the decoder to detect and decode all 16 DTMF tone-pairs into a 4-bit code. External ponent count is minimized by on-chip provision of a differential input amplifier, clock-oscillator and latched 3-state bus interface. • plete receiver in an 18-pin package. • Excellent performance. • CMOS, single 5 volt operation. • Minimum board area. • Central office quality. • Low power consumption.

S NAME ESt PIN 16 DESCRIPTION Early steering output.
Presents a logic high immediately when the digital algorithm detects a recognizable tone-pair (signal condition).
Any momentary loss of signal condition will cause ESt to return to a logic low.
