Typical Application (continued)

9.2.1 Design Requirements

For this design example, use the parameters listed in Table 3.

Table 3. Design Parameters

DESIGN PARAMETERS

EXAMPLE VALUES

Input voltage range

0.65 V to 3.6 V

Output voltage range

0.65 V to 3.6 V

9.2.2 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-Q1 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-Q1 determine the output

voltage range of the SN74AXC2T245-Q1.
