The HT6P20X series 224 OTP encoder 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. The combination of address and data bits of the HT6P20X is designed using one time programmable process. In addition, the chip offers various packaging for flexible combination of programmable ad- dress/data so as to meet various applications. Its pro- grammable address/data is transmitted together with the anti-code bits via RF or infrared transmission me- dium upon receipt of a trigger signal.
The HT6P20X series is a CMOS LSI one‑time programmable (OTP) encoder that stores up to 24 bits of address/data and transmits them serially via a DOUT pin. It features low power consumption, a built‑in oscillator requiring only a 5 % resistor, and minimal external components.
Typical applications include burglar and security alarms, smoke/fire detectors, cordless telephones, garage‑door controllers, and other remote‑control systems. The device is offered in 8‑pin DIP/SOP (HT6P20A/B) and 16‑pin DIP/NSOP (HT6P20D) packages, with detailed mechanical dimensions and carrier‑tape specifications provided.
