Req on 9572XL

Hi all,
Can XC9572XL drive 5Volt chip TTL without Level translaction?
Can XC9572XL drive 5V Max232 for pc serial port?
Can XC9272XL drive PC parallel port without buffer or level translaction?

Thanks
 

Re: Req on 9572XL

Regarding the parallel port, you should use a 74LV161284 (or similar) to meet IEEE-1284
 

Re: Req on 9572XL

XC9572XL can drive 5VTTL but I think level shifter must be used when connected to PC serial port.

Regards,
 

Re: Req on 9572XL

XC95xxXL's IO is 5v tolerant. It has no problem to drive 5V device. If you really want a 5V output without using a level shifter, you can use a pull up resistor to 5v and output high impedence.
