ICS8545I-02 Data Sheet

LOW SKEW, 1-TO-4 LVCMOS/LVTTL-TO-LVDS FANOUT BUFFER

AC Electrical Characteristics

NOTE: 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 equilibrium

has been reached under these conditions.

NOTE 2: Defined as skew between outputs at the same supply voltage and with equal load conditions.

NOTE 3: Defined as skew between outputs on different devices operating at the same supply voltages and with equal load conditions. Using

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

NOTE 4: This parameter is defined in accordance with JEDEC Standard 65.

NOTE 5: Measured using 50% duty cycle.
