General Description
The HT1613C 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 HT1613C can display the real time or be blank by
default. When answering a telephone call, the timer is
activated to tell users how long the conversation has
taken. The HT1613C receives dialing data from the di-
aleranddisplaysthephonenumberontheLCDfromleft
to right each time a phone call is made. By adding a
TIMER key, the HT1613C can provide the stopwatch
and timer reset/hold functions. Refer to the functional
description for details.
Applications
Timers, clocks and watches
LCD display drivers
Telephone display interface
Instrument display
Patent Number: 84545 (R.O.C.)
