General Description

The HT62104 devices are high performance infrared

remote control encoders which are manufactured in

silicon gate CMOS technology. The HT62104 devices

support eight data key inputs and an LED output to

indicate the transmission status. A signal transmission

is automatically activated when any key data input

lines change status from high to low.

The device generates a signal which is composed of a

Start code, a Custom code and a Data code and sends

the signal to its output pin. This can be provided to an

IR (38kHz carrier) transmission medium.
