Decoder BCD to DEC (1 from 8) not only for antenna switch

wiki order

This is simply but powerful decoder from BCD data to one of eight. You can use it everywhere you have less wires than you need. You need only 4 wires and control up to 8 outputs. You can supply external relays over the BCD data wires. There is universal output driver. You can drive outputs by switching to GND or + Vcc voltage. BCD inputs include RF and high voltage protection.
