HT1611C
Timer with Dialer Interface

General Description
The HT1611C is a CMOS chip designed for dialer inter-
faces driving 8 or 10-digit LCDs. Various functions, such
as real time clock, dialing number and conversation time
display are provided.
The real time is displayed by default. When answering a
telephone call, the timer is activated to tell users how
long the conversation has taken. After the telephone is
hung up, the total conversation time is shown for about 5
seconds and then the real time is displayed again.
When making a phone call, the HT1611C receives the
dialing data from the dialer and displays the phone num-
ber from left to right on the LCD. However, if there is no
dialing action within 10 seconds, it restarts the timer
again. By adding a TIMER key, the HT1611C can pro-
vide a stopwatch function and timer reset/hold functions
(for details, refer to the functional description).
