Revised January 2003 100EL11 5V ECL 1:2 Differential Fanout Buffer General Description Features 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. ■ Typical propagation delay of 265 ps 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. ■ Typical IEE of 26 mA ■ Typical Skew of 5 ps between outputs ■ Internal pull-down resistors on inputs ■ Fairchild MSOP-8 package is a drop-in replacement to ON TSSOP-8 ■ Meets or exceeds JEDEC specification EIA/JESD78 IC latch-up test ■ Moisture Sensitivity Level 1 ■ ESD Performance: Human Body Model > 2000V Machine Model > 200V Ordering Code: Product Order Number Package Code Package Description Number Top Mark 100EL11M 100EL11M8 (Preliminary) M08A KEL11 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow MA08D KL11 8-Lead Molded Small Outline Package (MSOP), JEDEC MO-187, 3.0mm Wide Devices also available in Tape and Reel.

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. 100EL PECL DC Electrical Characteristics VCC = 5.0V; VEE = 0.0V (Note 2) Symbol Parameter −40°C Min 25°C Typ Max 26 31 Min 85°C Typ Max 26 31 Max 30 36 mA 3975 4050 4120 mV 3380 3190 3295 3380 mV 3835 4120 3835 4120 mV 3525 3190 3525 3190 3525 mV 4.6 2.5 4.6 2.5 4.6 V 150 µA Power Supply Current VOH Output HIGH Voltage (Note 3) 3915 3995 4120 3975 4045 4120 VOL Output LOW Voltage (Note 3) 3170 3305 3445 3190 3295 VIH Input HIGH Voltage (Single Ended) 3835 4120 VIL Input LOW Voltage (Single Ended) 3190 VIHCMR Input HIGH Voltage Common Mode 2.5 Range (Differential) (Note 4) IIH Input HIGH Current (Note 5) IIL Input LOW Current (Note 5) Units Typ IEE 150 0.5 Min 150 0.5 0.5 µA Note 2: Input and output parameters vary 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. www.fairchildsemi.com 2 Symbol −40°C Parameter Min Typ 25°C Max Min Typ 85°C Max Min Typ Max Units IEE Power Supply Current 26 31 26 31 30 36 mA VOH Output HIGH Voltage (Note 7) −1085 −1005 −880 −1025 −955 −880 −1025 −955 −880 mV −1695 −1705 −1705 −1620 mV VOL Output LOW Voltage (Note 7) −1830 −1555 −1810 −1620 −1810 VIH Input HIGH Voltage (Single Ended) −1165 −880 −1165 −880 −1165 −880 mV VIL Input LOW Voltage (Single Ended) −1810 −1475 −1810 −1475 −1810 -1475 mV VIHCMR Input HIGH Voltage Common Mode −2.5 −0.4 −2.5 −0.4 −2.5 −0.4 V 150 µA Range (Differential) (Note 8) IIH Input HIGH Current (Note 9) IIL Input LOW Current (Note 9) 150 0.5 150 0.5 µA 0.5 Note 6: Input and output parameters vary 1 to 1 with VCC.
