HT9170B General Description

The HT9170B/D are Dual Tone Multi Frequency (DTMF) receivers integrated with digital decoder and bandsplit filter functions as well as power-down mode and inhibit mode operations. Such devices use digital counting techniques to detect and decode all the 16 DTMF tone pairs into a 4-bit code output.

Highly accurate switched capacitor filters are implemented to divide tone signals into low and high group signals. A built-in dial tone rejection circuit is provided to eliminate the need for pre-filtering.

HT9170B Maximum Ratings

Supply Voltage ........................................-0.3V to 6V
Storage Temperature .........................-50 to 125
Input Voltage...........................VSS-0.3V to VDD+0.3V
Operating Temperature..........................-20 to 75

Note: These are stress ratings only. Stresses exceeding the range specified under "Absolute Maximum Ratings"may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliability.

HT9170B Features

· Operating voltage: 2.5V~5.5V
· Minimal external components
· No external filter is required
· Low standby current (on power down mode)
· Excellent performance
· Tristate data output for MCU interface
· 3.58MHz crystal or ceramic resonator
· 1633Hz can be inhibited by the INH pin
· HT9170B: 18-pin DIP package
    HT9170D: 18-pin SOP package
