I am trying to use the HI or LO output from pin 8 on two NE567 tone decoders to trigger an H-Bridge motor reverser. My H-Bridge is set up so that if both inputs are the same, the motor is off. It works fine when the two inputs are connected to HI or LO from the power supply, but when connected to the normally HI outputs of the NE567's the BJT's get hot. The HI output from the NE567's doesn't seem to be able to supply enough current to trigger the BJT's. It barely lights an LED. I tried using a FET to amplify the current from the 567's, but I couldn't get it to work. The H-Bridge is made of two NPN and two PNP bipolar transistors. Maybe I need to use MOSFETS in the H-Bridge instead of BJT's? Would they be simpler to trigger? Any help would be greatly appreciated. Thanks.
