SK10/100EL11W
1:2 Differential
Fanout Buffer
Description
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.
Features
• 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
V
EE
• 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

AC Characteristics (continued)
Notes:
1. 10EL circuits are designed to meet the DC specifications shown in the table after thermal
equilibrium has been established. 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 T
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
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.
