* Values are with terminations as per Figure 4 or equivalent.
† The input levels and difference voltage provide zero noise immunity and should be tested only in a static, noise-free environment.
‡ Test must be performed one lead at a time to prevent damage to the device.
§ See Figure 1 for BPPGA terminations.
