Hello

Wondering if someone can help 

I am having troubles spotting the minimum voltage swing for a GPS voltage on a PIC16F628 PIC MCU USART

http://ww1.microchip.com/downloads/en/devicedoc/40300c.pdf

I want to use Scotts TTL GPS but I need to make sure it swings high enough to make 1 and 0

So I can do away with the MAX232 chip I am using now
