Features The little external components.The low external power supply voltage, the value is 2-6.5V.The modulation frequency is 455kHz, we can use this frequency to prevent the interference of the fluorescent lamp.In the non-operating state, the power supply current is very small, the value is lower than 4uA when VDD=6V.It has 20 groups of subsystem addresses, every subsystem has 64 instructions.The instruction is transmitted with the pulse intermission pulse coding method, there are two methods: the infrared flash pulse and the modulating pulse. The infrared flash pulse requires the receiving system to use the broadband preamplifier to restrain the noise, the modulating pulse allows the receiving system to use the narrowband preamplifier to restrain the noise.The 20-pin dual-row DIP package.
