You have to use level converteres for example to convert from a RS232/TTL when levels are pretty different, but in this case it should work OK.
Since TTL levels are somewhat VH = 2V and VL = 0.8 (aprox), you can use a 3.3V chip if it can tolerate the 5V from the other side, sometimes the chip doesn't support input voltages larger than VDD + 0.6 Volts, and that could damage the chip. Regards Robert. |
