Overview
HT6P20X Series 224 OTP Encoder 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 · HT6P20A/B: 8-pin DIP/SOP package HT6P20D: 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 General Description The HT6P20X 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 address/data so as to meet various applications.
Its programmable address/data is transmitted together with the anti-code bits via RF or infrared transmission medium upon receipt of a trigger signal.
