13 MEMORY TONE / PULSE DIALER
WITH REDIAL SAVE HANDFREE &
HOLD FUNCTION
DESCRIPTION
The SC91650A/B, SC91651A/B, SC91652A/B are 13-memory
Tone/Pulse switchable dialer with Last Number Redial(LNB) and
HOLD function, which are fabricated in COMS technology with wide
operating voltage for both tone and pulse mode, and consumes very
low memory retention current in ON-HOOK state.
DIP-18
DIP-22
FEATURES
*13-memory Tone/Puls e switchable dialer
*Three 16-digit one touch memory and ten 16-digit two touch
memory
One 32-digit last number redial memory
One 32-digit SAVE function for storing phone number in off hook
status
Note: only 15-digit/31-digit for Tone mode, 1-digit use to identify
tone mode
*Power on reset circuit is provided
*Hold function is provided
* Keytone is provided
*Pulse-to-tone (P→T) is provided for PBX operation
*Flash key is available
*Packaged in 18-DIP or 22-DIP
*Minimum tone duration is 100ms for SC91650, SC91651 or 91ms
for SC91652
*Minimum intertone pause is 106ms for SC91650, SC91651 or
91ms for SC91652
*Uses 3.579545MHz crystal or ceramic resonator
*Many options can be selected
