Hardware Setup

This section covers the five steps needed to get started when using this EVM to evaluate an NL logic or translation device, which are as follows:

  1. Identify the desired package for the device being evaluated. As stated previously, this EVM has nine sections each of which contains a footprint for one of the packages mentioned. Break off the selected section (optional).
  2. Solder down the device. Figure 2-2 shows an example of proper placement.

  3. Ensure the EVM is configured accordingly for dual supply or single supply device. The EVM comes default configured for dual supply devices, but is easily configured using a 0-Ω resistor for single supply devices. Figure 2-3 shows how this is done.

  4. Interface with device pins. The kit includes twelve 12-pin headers and eight supply test points which will allow the user to fully populate two sections (headers can be broken apart for lower pin counts). An example of this, with the addition of bypass capacitors for the supplies, as shown in Figure 2-4.

  5. Before applying power to the EVM, ensure the proper supply configuration is in place to avoid shorting two supplies together.
