W91510DN - TONE/PULSE DIALER

Description

The W91510DN series ICs are Si-gate CMOS IC that provide the signals needed for either pulse or tone dialing.

They feature a 12/16-digit LCD driver for displaying telephone numbers and calling time.

A real time clock is included to display the time of day.

Features

  • One by 32 digits for redial.
  • Uses 5 × 6 keyboard.
  • Pause, pulse-to-tone (.
  • /T) can be stored as a digit in memory.
  • Flash can be stored as a digit in memory when in store mode.
  • Minimum tone output duration: 87 mS.
  • Minimum intertone pause: 87 mS.
  • Tone/pulse mode pin selectable.
  • Make/break ratio pin selectable.
  • Dialing rate: 10 ppS.
  • Pause time: 3.6 Sec.
  • Flash break time (73 mS, 100 mS, 300 mS or 6.
