#104557 - 5V tolerant? Responding to: ???'s previous message |
Mark Bongers said:
The inputs are 5V tolerant. [...] Can the P89LPC920 output buffer handle the 5V that is provided by the 10k resistor (as output)? And can the P89LPC920 make the signal low? Well, I thought "5V tolerant" means that as long as you don't violate the maximum output current you should be able to do this... What does the datasheet say? A sidenote, Philips has somewhere an appnote how to interface 3V and 5V correctly (using a FET) - the appnote is targeted for I2C but is perfectly valid for any other 3V/5V interface. Jan Waclawek |
