Do you mean 47 ohm in series with the 74HC14 output, to isolate the chip from the kabel and the "nasty outside world", or did I get it wrong? Yes, 47 ohms in between the chip and the cable. It's not so much to protect the driver from the outside world; rather, it's so you can match the driver impedance to the cable's impedance. -a |
