Revised January 2003 100LVEL11 3.3V ECL 1:2 Differential Fanout Buffer General Description Features The 100LVEL11 is a low voltage 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 330 ps ■ Typical IEE of 24 mA ■ Typical skew of 5 ps between outputs ■ Internal pull-down resistors on D With inputs Open or both inputs at VEE, the differential Q outputs default LOW and Q outputs default HIGH. ■ Fairchild MSOP-8 package is a drop-in replacement to ON TSSOP-8 The 100 series is temperature compensated. ■ Meets or exceeds JEDEC specification EIA/JESD78 IC latch-up tests ■ Moisture Sensitivity Level 1 ■ ESD Performance: Human Body Model > 2000V Machine Model > 200V Ordering Code: Package Order Number Number Product Code Package Description Top Mark 100LVEL11M M08A KVL11 8-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150" Narrow 100LVEL11M8 (Preliminary) MA08D KV11 8-Lead Molded Small Outline Package (MSOP), JEDEC MO-187, 3.0mm Wide Devices also available in Tape and Reel.

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 24 28 24 28 25 30 mA VOH Output HIGH Voltage (Note 7) −1085 −1005 −880 −1025 −955 −880 −1025 −955 −880 mV VOL Output LOW Voltage (Note 7) −1830 −1695 −1555 −1810 −1705 −1620 −1810 −1705 −1620 mV 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 VPP < 500mV −2.1 −0.2 −2.2 −0.2 −2.2 −0.2 VPP ≥ 500mV −1.9 −0.2 −2.0 −0.2 −2.0 −0.2 Range (Differential) (Note 8) IIH Input HIGH Current (Note 9) IIL Input LOW Current (Note 9) 150 150 150 D 0.5 0.5 0.5 D −600 −600 −600 V µA µA Note 6: Input and output parameters vary 1 to 1 with VCC.
