Decoder BCD to 16 (Yaesu band decoder) not only for antenna switch

wiki order

This is simply but powerful decoder from BCD data input to 16 outputs, compatible with Yaesu BCD (Yaesu BCD decoder). You can use it everywhere you have less wires than you need and also with BCD (TTL) output devices (like Microham). You need only 4 wires and control up to 16 outputs. There is universal output driver. You can drive outputs by switching to GND or + Vcc (EXT) voltage. BCD inputs include RF and high voltage protection. Optional PTT input works as Hot Switch protection.
