DESIGN PARAMETERS

EXAMPLE VALUES

Input voltage range

0.65V to 3.6V

Output voltage range

0.65V to 3.6V

8.2.2 Detailed Design Procedure

To begin the design process, determine the following:

• Input voltage range

– Use the supply voltage of the device that is driving the SN74AXC2T245 device to determine the input

voltage range. For a valid logic high, the value must exceed the high-level input voltage (VIH) of the input

port. For a valid logic low the value must be less than the low-level input voltage (VIL) of the input port.

• Output voltage range

– Use the supply voltage of the device being driven by the SN74AXC2T245 determine the output voltage

range of the SN74AXC2T245.
