lvttl & ttl
Thanks for the reply. I am actually not so much concerned with the 5V to 3.3V shift. As stated in the previous post there is the clamping diode and I can use a series resistor to reduce the voltage amount. I am actually more concerned with the 3.3V to 5V. This will be evident...
convert ttl to lvttl
I am trying to interface an 8-bit microcontroller to a spartan III development board (digilent) which is similar to one of the posts above. The Spartan III also only supports LVTTL. Someone said earlier that 3.3V on the chip would be considered logic 1(high)... What chip...
