General Description

The HT7704 series are CMOS LSIs in 8-lead DIP

package. They are designed to control the bright-

ness of an incandescent lamp by changing the

triggering angles of the TRIAC with touch sense

input.

switch function dimmer. High sensitivity and

stability account for its eminent performance.

The sense input can sustain very heavy capaci-

tive loading and propagate sense through a

highly resistive line. In addition, the applica-

tion circuit is very simple.

HT7704 is a selectable 3-step, 4-step or on/off
