100EL11 5V ECL 1:2 Differential Fanout Buffer
January 2003 Revised January 2003
100EL11 5V ECL 1:2 Differential Fanout Buffer
General Description
The 100EL11 is a 5V 1:2 differential fanout buffer. One differential input signal is fanned out to two identical differential outputs. By supplying a constant reference level to one input pin a single ended input condition is created. With inputs open or both inputs at VEE the differential Q outputs default LOW and Q outputs default HIGH. The 100 series is temperature compensated.
Features
s Typical propagation delay of 265 ps s Typical IEE of 26 mA s Typical Skew of 5 ps between outputs s Internal pull-down resistors on inputs s Fairchild MSOP-8 package is a drop-in replacement to ON TSSOP-8 s Meets or exceeds JEDEC specification EIA/JESD78 IC latch-up test s Moisture Sensitivity Level 1 s ESD Performance: Human Body Model > 2000V Machine Model > 200V

Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The "Recommended Operating Conditions" table will define the conditions for actual device operation.

Note 2: Input and output parameters vary 1 to 1 with VCC. VEE can vary +0.8V/-0.5V. Note 3: Outputs are terminated through a 50 Resistor to VCC - 2.0V. Note 4: VIHCMR minimum varies 1 to 1 with VEE. VIHCMR maximum varies 1 to 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 1V. Note 5: Absolute value of the input HIGH and LOW current should not exceed the absolute value of the stated MIn or Max specification. Note: Devices are designed to meet the DC specifications after thermal equilibrium has been established. Circuit is tested with air flow greater than 500LFPM maintained.
