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. Electrical parameters are guaranteed only over the declared
operating temperature range. Functional operation of the device exceeding these conditions is not implied. Device specification limit
values are applied individually under normal operating conditions and not valid simultaneously.
4. Measured with 750 mV (LVPECL) source or 1 V (HSTL) source, 50% duty cycle clock source. All outputs loaded with 50 W to ground
5. Skew is measured between outputs under identical transitions and conditions on any one device.
6. DevicetoDevice skew for identical transitions at identical VCC levels.
7. OE Set Up Time is defined with respect to the rising edge of the clock. OE HightoLow transition ensures outputs remain disabled during
the next clock cycle. OE LowtoHigh transition enables normal operation of the next input clock (See Figure
7).8. VPP is the differential input voltage swing required to maintain AC characteristics including tPD and devicetodevice skew.
