BCD to 16 converter manual

This converter/decoder BCD to 16 is a simply but very powerful device. It decodes from BCD data input to 16 outputs. 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.
