HT9201B - (HT9201A/B) Simple Tone Dialer

Download the HT9201B datasheet PDF. This datasheet also covers the HT9201A variant, as both devices belong to the same (ht9201a/b) simple tone dialer family and are provided as variant models within a single manufacturer datasheet.

Description

The HT9201A/B tone dialers are CMOS LSIs designed for telecommunication systems.

The HT9201A is for mute output whereas the HT9201B is for flash output.

Both dialers provide good performance for regular DTMF dialing with low distortion output and minimal external components.

Features

  • Patent Number: 113235(R. O. C. ), 5424740(U. S. A. ).
  • Operating voltage: 2.0V~5.5V Low standby current 4×4 keyboard matrix 3.58MHz crystal or ceramic resonator Four flash key times selectable for the HT9201B General.
