SK10/100EL11W 1:2 Differential Fanout Buffer HIGH-PERFORMANCE PRODUCTS Description Features • The SK10/100EL11W is a differential 1:2 fanout buffer. This device is fully compatible with MC10/100EL11 and MC100LVEL11. With output transition time much faster than the E111, the EL11W is ideally suited for those applications which require ultimate AC performance. • • • • • Under open input conditions, the pulldown resistors will force the Q0 and Q1 outputs low and Q0* and Q1* high. • • • • • Functional Block Diagram PIN Names Q0 1 8 VCC Q0* 2 7 D Q1 3 6 D* Q1* 4 5 VEE Revision 1/February 12, 2001 Extended Supply Voltage Range: (VEE = –5.5V to –3.0V, VCC = 0V) or (VCC = + 3.0V to +5.5V, VEE=0V) High Bandwidth Output Transition 330 ps Propagation Delay 5 ps Skew Between Outputs Internal Input Pulldown Resistors Q Output will Default Low with Inputs Open or at VEE New Differential Input Common Mode Range Fully compatible with MC10/100EL11 and MC10/100LVEL11 ESD Protection of >4000V Industrial Temperature Range: –40oC to +85oC Available in both 8 Pin SOIC (150 mils ) and MSOP (3mm x 3mm) Packages 1 Pin Function D, D* Differential data Inputs Q0, Q0*, Q1, Q1* Differential data Outputs www.semtech.com SK10/100EL11W HIGH-PERFORMANCE PRODUCTS Package Information 8 Pin SOIC Package PIN Descriptions END VIEW TOP VIEW A D 8 C 5 H E 0.25 M B M 1 4 B h x 45o q e A Seating Plane C L 0.10 A1 B 0.25 M C B S A S MILLIMETERS DIM MIN MAX A 1.35 1.75 A1 0.10 0.25 B 0.33 0.51 C 0.19 0.25 D 4.80 5.00 E 3.80 4.00 e 1.27 BSC H 5.80 6.20 h 0.25 0.50 L 0.40 1.27 θ 0o 8o Revision 1/February 12, 2001 NOTES: 1.

The circuit is in a test socket or mounted on a printed circuit board and transverse airflow greater than 500 lfpm is maintained. Outputs are terminated through a 50Ω resistor to VCC -2.0V except where otherwise specified on the individual data sheets. 2. 100K circuits are designed to meet the DC specifications shown in the table where transverse airflow greater than 500 lfpm is maintained. 3. Within-device skew defined as identical transitions on similar paths through a device. 4. Duty cycle skew is the difference between a TPLH and TPHL propagation delay through a device. 5. Minimum input swing for which AC parameters guaranteed. 6. CMR 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 VPP(min) and 1V. The lower end of the CMR range varies 1:1 with VEE and is equal to VEE + 1.6V. 7. For standard ECL DC specifications, refer to the ECL Logic Family Standard DC Specifications Data Sheet. 8.
