dB
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.
2. Measured from the differential input crossing point to the differential output crossing point
3. Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at the differential cross points.
4. This parameter is defined in accordance with JEDEC Standard 65.
5. 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.
6. Qx, nQx outputs measured differentially. See MUX Isolation diagram in the Parameter Measurement Information section.
