EM91240C Description

TONE/PULSE SWITCHABLE DIALER WITH LCD INTERFACE TONE/PULSE SWITCHABLE DIALER WITH LCD INTERFACE EM91240 SERIES EM91240 SERIES GENERAL .
The EM91240 is a series of tone/pulse switchable dialers that is composed of T/P dialer and T/P dialer with 40-set memories.

EM91240C Features

* Tone/Pulse switchable.
* Wide operating voltage from 2.0 V to 5.5 V.
* Low operating current, 0.15 mA (Pulse) and 0.3 mA (Tone) typically.
* Adding resistor on keyboard scan pin that can select many telephone specifications, such as : Pulse rate, M/B ratio, Flash ti

EM91240C Applications

* Storing : EM91240 series support two operating methods to store numbers into SAVE redial memory. Method 1
* To select Pulse or Tone mode.
* Off-hook (or turn on HF function), push d1, d2, . . , dn. The numbers d1, d2, . . , dn will be dialed out in Pulse or Tone mode as selection.
