MC100LVEL37 3.3 V ECL 1:4 /1//2 Clock Fanout Buffer Description The MC100LVEL37 is a fully differential 1:4 fanout buffer. The device offers two outputs at /1 of the input frequency, and two outputs at /2 of the input frequency. The Low Output-Output Skew of the device makes it ideal for distributing 1x and 1/2x frequency synchronous signals. The differential inputs have special circuitry which ensures device stability under open input conditions. When both differential inputs are left open the CLKn input will pull down to VEE, The CLKn input will bias around VCC/2 and the Qn output will go LOW. www.onsemi.com SOIC-20 WB DW SUFFIX CASE 751D-05 Features * 700 ps Typical Propagation Delays * 50 ps Maximum Output-Output Skews * ESD Protection: MARKING DIAGRAM* > 2 kV Human Body Model > 200 V Machine Model The 100 Series Contains Temperature Compensation PECL Mode Operating Range: VCC = 3.0 V to 3.8 V with VEE = 0 V NECL Mode Operating Range: VCC = 0 V with VEE = -3.0 V to -3.8 V Internal Input Pulldown Resistors Qn Output will Default LOW with Inputs Open or at VEE Meets or Exceeds JEDEC Spec EIA/JESD78 IC Latchup Test Moisture Sensitivity: Level 3 (Pb-Free) (For Additional Information, see Application Note AND8003/D) Flammability Rating: UL 94 V-0 @ 0.125 in, Oxygen Index 28 to 34 Transistor Count = 256 Devices These Devices are Pb-Free, Halogen Free and are RoHS Compliant * * * * * * * * * * 20 100LVEL37 AWLYYWWG 1 A WL YY WW G = Assembly Location = Wafer Lot = Year = Work Week = Pb-Free Package *For additional marking information, refer to Application Note AND8002/D.

Device specification limit values are applied individually under normal operating conditions and not valid simultaneously. 1. Input and output parameters vary 1:1 with VCC. VEE can vary 0.3 V. 2. Outputs are terminated through a 50 W resistor to VCC - 2.0 V. 3. VIHCMR min varies 1:1 with VEE, max varies 1:1 with VCC. The VIHCMR range is referenced to the most positive side of the differential input signal. Normal operation is obtained if the HIGH level falls within the specified range and the peak-to-peak voltage lies between VPPmin and 1 V. Table 5.
