HT12E remote control encoder IC(DIP)

The HT12E is a series encoder IC from the HT12 family, designed by Holtek for remote control and serial data transmission applications. It converts 4 bits of parallel data into a serial format compatible with RF or infrared transmitter modules.

Specifications

• Manufacturer : Holtek
• Type : Remote Control Encoder
• Packaging : DIP18 (Through-Hole Technology)
• Supply Voltage : 2.4 V to 12 V DC
• Operating Frequency : Typically 38 kHz
• Current Consumption : Max 400 µA
• Data Pins : 4 parallel inputs (D0-D3)
• Output : Serial data with Enable (OE) and Data Lock (DL) control

This component is often paired with the HT12D decoder to create simple wireless communication links between microcontrollers (Arduino, ESP32, etc.). It typically requires an external crystal oscillator to set the operating frequency.
