AC Electrical Characteristics

Note 1.

1.

Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is

mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equi-

librium has been reached under these conditions.

6.

Defined as skew between outputs on different devices operating at the same supply voltage, same frequency, same temperature and with

equal load conditions. Using the same type of inputs on each device, the outputs are measured at the differential cross points.
