General Description
The HT6P20 is a CMOS LSI encoder designed for remote control system applications. It encodes 24 bits of information and then serially transmits it via the DOUT pin upon receipt of transmission enable (DATA pins: D0~D7) signals.

FEATUREs
• Operating voltage: 2V~12V
• Low power consumption
• Built-in oscillator needs only 5% resistor
• 0/2/4/8 data selectable
• 224 maximum address and data codes
• Easy interface with an RF or IR medium
• One time programmable process
• Data active: D0~D7
• Minimal external components
• HT6P20/A/B: 8-pin DIP/NSOP package HT6P20/D: 16-pin DIP/NSOP package

APPLICATIONs
• Burglar alarm system
• Smoke and fire alarm system
• Garage door controllers
• Car door controllers
• Security system
• Cordless telephones
• Other remote control systems
