NOTES:

1. Parametric values specified at:

5 volt Power Supply Range 100EL38 Series:

-4.2V to -5.5V.

10EL38 Series

-4.75V to -5.5V.

3 volt Power Supply Range 10/100EL38L Series: -3.0V to -3.8V.

2. Skew is measured between outputs under identical transitions.

3. Minimum input swing for which AC parameters are guaranteed. The device will function reliably with differential inputs down to 100mV.

4. The 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. The numbers in the spec table

assume a nominal VEE = –3.3V. Note for PECL operation, the VCMR (min) will be fixed at 3.3V – IVCMR (min)I.
