NOTE: Device will meet the specifications after thermal equilibrium has been established when mounted in a test socket or printed circuit
board with maintained transverse airflow greater than 500 lfpm.
3. Characterized up to F

≤ 150 MHz.
4. Measured from the V
DD
/2 of the input to V
DD
/2 of the output.
5. This parameter is defined in accordance with JEDEC Standard 65.
6. Defined as skew between outputs at the same supply voltage and with equal load conditions. Measured at V
DD
/2.
7. Defined as skew between outputs on different devices operating at the same supply voltage, same temperature, same frequency and with
equal load conditions. Using the same type of inputs on each device, the outputs are measured at V
DD
/2.
8. With rail to rail input clock.
