MC100LVEL13 3.3V ECL Dual 1:3 Fanout Buffer Description The MC100LVEL13 is a dual, fully differential 1:3 fanout buffer. The Low Output−Output Skew of the device makes it ideal for distributing two different 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 D input will pull down to VEE, The D input will bias around VCC/2 and the Q output will go LOW. http://onsemi.com Features • • • • • • • • • • • • 500 ps Typical Propagation Delays 50 ps Output−Output Skews ESD Protection: >2 kV Human Body 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 Q Output will Default LOW with Inputs Open or at VEE Meets or Exceeds JEDEC Spec EIA/JESD78 IC Latchup Test Moisture Sensitivity: Pb = Level 1 Pb−Free = Level 3 For Additional Information, see Application Note AND8003/D Flammability Rating: UL 94 V−0 @ 0.125 in, Oxygen Index: 28 to 34 Transistor Count = 143 devices SO−20 WB DW SUFFIX CASE 751D MARKING DIAGRAM* 20 100LVEL13 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.
