Product details

Description

The HT1330 is a CMOS fabricated LSI chip designed to drive a standard three and 1/2 digit biplexed LCD for a count-up/down timer in watch applications.

The watch and timer are based on a 32768Hz quartz crystal oscillator.

The maximum count-down time is 20 hours with an accuracy of 1 second.

Features
