General Description

The HT6026 is a CMOS LSI encoder designed for

use in remote control system. It is capable of

encoding 9 bits of information which consists of N

address bits and 9–N data bits. Each address/data

input is externally trinary programmable by ex-

ternal switches. The programmable address/data

Pin Assignment

• Two transmission words minimum

• Built-in oscillator needs only 5% resistor

• Interface with RF or infrared transmission

medium

• Minimal external components

• Security system

• Cordless telephones

• Other remote control systems

is transmitted along with the header bits via an

RF or an infrared transmission medium upon

receipt of a trigger signal (TE).

The HT6026 is pin compatible with the

MC145026.
