HT9170B Product details

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.

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 General.
