HT62104 -- Infrared Remote Encoder

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.
