LC7385

The LC7385 is designed as one kind of DTMF receiver LSIs integrate bandsplit filter and digital decoder functions for the 16 DTMF digits used in touch-tone telephone systems.

Features of the LC7385 are:(1)detects all 16 DTMF signals;(2)includes on-chip all filters required in a DTMF receiver;(3)extended dynamic range;(4)serial data output;(5)low-power double-poly CMOS process;(6)user-selectable acquisition and release times;(7)3-state data outputs facilitate microcontroller or other peripheral interfaces;(8)standby mode;(9)built-in differential input amplifier.

The absolute maximum ratings of the LC7385 can be summarized as:(1)maximum supply voltage: -0.3 to +7.0 V;(2)maximum input voltage: -0.3 to VDD+0.3 V;(3)maximum input current: -10 to +10 mA;(4)maximum output voltage: -0.3 to VDD+0.3 V;(5)power dissipation: 250 or 180 mW;(6)operating temperature: -40 to +85 ;(7)storage temperature: -50 to +125 .
