PIN ASSIGNMENTS
* This specification are subject to be changed without notice.
The EM91710A/B are Tone/Pulse switchable dialer which are fabricated in CMOS technology with wide
operating voltage for both tone and pulse mode, and consumes very low memory retention current in ON-HOOK
state.
• Tone/pulse switchable dialer.
• One 32-digit last number redial memory.
• Pulse to tone (P T) is provided for PBX operation.
• Flash key is available.
• Minimum tone duration is 98ms or 83ms.
• Minimum intertone pause is 98ms or 83ms.
• Uses 3.579545 MHz crystal or ceramic resonator.
• Many options can be selected.
• Flash function (RESET)
• Mixed dialing.
• Handfree function is provided for speaker phone application.
• Power on reset circuit is provided.
• Package in DIP18 or DIP16.
Mode (10 PPS ; 20 PPS ; Tone)
M/B ratio (40 : 60 ; 33 : 66)
Pause time (3.6s)
P T pause time (3.6s)
Flash time (600ms; 300ms; 100ms; or 80ms).
