I am trying to produce 5V PWM signals to feed to motor drivers. These PWM signals originally come from a PIC microcontroller, which typically produces 5V PWM signals, which is what I need. But I need to feed them through a 74LS245 transceiver to the drivers because I want to be able to disable PWM feeding whenever I enable the "E" pin of the transceiver. But the transceiver reduces the 5V PWM amplitude to at most 3.4V, which is not enough. So I need to amplify these PWM signals from the transceiver. (BTW, I'm using the transceiver here as a buffer)
Thanks very much!
